PHP gmp_gcd() Function

PHP language uses the gmp_gcd() mathematical function to figure out the greatest common divisor of a GMP parameter. This function displays the GCD value in a single line.

Syntax

The given syntax shows the required data for PHP gmp_gcd() function.

Parameters

As shown in the above syntax, this function requires two GMP number as a required parameter.
It can be a GMP object or numbers to get the largest or greatest common divisor into two parameters.

Return Values

This function gives back a GMP number as an output that is the largest common divisor of the parameter.

Examples

The given examples show the greatest common divisor of the different types of GMP parameters.

Example1: the given example shows a GCD operation with given GMP parameters. Here, we can use the numerical number to find the largest common divisor number.

<!DOCTYPE html>
<html>
<body>
<h4> PHP gmp_GCD() Function </h4>
<?php
echo "<p> Display greatest common value of the given data </p>";
$value1 = gmp_gcd(3, 12);
$input1 = gmp_strval($value1);
$value2 = gmp_gcd(12, 24);
$input2 = gmp_strval($value2);
$value3 = gmp_gcd(18, 24);
$input3 = gmp_strval($value3);
echo " The GCD number of the GMP parameters:  <b>" .$input1. "</b>";
echo "<br/>";
echo " The GCD number of the GMP parameters:  <b>" .$input2. "</b>";
echo "<br/>";
echo " The GCD number of the GMP parameters:  <b>" .$input3. "</b>";
?>
</body>
</html>

Output:

The following output image shows gmp_gcd() functions value.

Example2: the given example shows a GCD operation with given GMP parameters. Here, we can use the negative number to find the largest common divisor number. The negative number displays the same greatest common divisor as a positive number.

<!DOCTYPE html>
<html>
<body>
<h4> PHP gmp_GCD() Function </h4>
<?php
echo "<p> Display greatest common value of the given data </p>";
$value1 = gmp_gcd(-3, -12);
$input1 = gmp_strval($value1);
$value2 = gmp_gcd(-12, 24);
$input2 = gmp_strval($value2);
$value3 = gmp_gcd(18, -24);
$input3 = gmp_strval($value3);
echo " The GCD number of the GMP parameters:  <b>" .$input1. "</b>";
echo "<br/>";
echo " The GCD number of the GMP parameters:  <b>" .$input2. "</b>";
echo "<br/>";
echo " The GCD number of the GMP parameters:  <b>" .$input3. "</b>";
?>
</body>
</html>

Output:

The given output image shows gmp_gcd() functions value.

Example3: the given example shows a GCD operation with given GMP parameters. Here, we can use the numerical variable to find the greatest common divisor.

<!DOCTYPE html>
<html>
<body>
<h4> PHP gmp_GCD() Function </h4>
<?php
echo "<p> Display greatest common value of the given data </p>";
$number1 = "50";
$number2 = "24";
$number3 = "2";
$number4 = "3";
$value1 = gmp_gcd($number1, $number2);
$input1 = gmp_strval($value1);
$value2 = gmp_gcd($number2, $number3);
$input2 = gmp_strval($value2);
$value3 = gmp_gcd($number2, $number4);
$input3 = gmp_strval($value3);
echo " The GCD number of the GMP parameters:  <b>" .$input1. "</b>";
echo "<br/>";
echo " The GCD number of the GMP parameters:  <b>" .$input2. "</b>";
echo "<br/>";
echo " The GCD number of the GMP parameters:  <b>" .$input3. "</b>";
?>
</body>
</html>

Output:

The following output image shows gmp_gcd() functions value.

Example4: the given example shows the greatest common divisor operation with given GMP parameters. Here, we can use the non-divisible GMP input numbers.

<!DOCTYPE html>
<html>
<body>
<h4> PHP gmp_GCD() Function </h4>
<?php
echo "<p> Display greatest common value of the given data </p>";
$number1 = "27";
$number2 = "29";
$number3 = "2";
$number4 = "3";
$value1 = gmp_gcd($number1, $number2);
$input1 = gmp_strval($value1);
$value2 = gmp_gcd($number2, $number3);
$input2 = gmp_strval($value2);
echo " The GCD number of the GMP parameters:  <b>" .$input1. "</b>";
echo "<br/>";
echo " The GCD number of the GMP parameters:  <b>" .$input2. "</b>";
?>
</body>
</html> 

Output:

The following output image shows gmp_gcd() functions value. the output shows the "1" value for the non-divisor number.

Example5: the given example shows the greatest common divisor operation with given GMP parameters. Here, we can use other GMP function with the input numbers. The example uses add function with variable values and uses in the GCD function./p>

<!DOCTYPE html>
<html>
<body>
<h4> PHP gmp_GCD() Function </h4>
<?php
echo "<p> Display greatest common value of the given data </p>";
$number1 = "27";
$number2 = "29";
$number3 = "12";
$number4 = "3";
$add_value1 = gmp_add($number1, $number2);
$add_value2 = gmp_add($number4, $number2);
$value1 = gmp_gcd($add_value1, $number3);
$input1 = gmp_strval($value1);
$value2 = gmp_gcd($add_value2, $number3);
$input2 = gmp_strval($value2);
$value3 = gmp_gcd($add_value1, $add_value2);
$input3 = gmp_strval($value3);
echo " The GCD number of the GMP parameters:  <b>" .$input1. "</b>";
echo "<br/>";
echo " The GCD number of the GMP parameters:  <b>" .$input2. "</b>";
echo "<br/>";
echo " The GCD number of the GMP parameters:  <b>" .$input3. "</b>";
?>
</body>
</html> 

Output:

The given output image shows gmp_gcd() functions value.

Conclusion

The gmp_gcd() function uses mathematical operations to get the greatest common divisor. This function helps to reduce code size using a single function and gets output easily.
