The gmp_lcm() is an inbuilt function in PHP that is used to calculate the least common multiple (LCM) of two or more integers.
Syntax:
gmp_lcm(GMP|int|string $num1, GMP|int|string $num2): GMP
Parameters: This function accepts two parameters that are described below.
- $num1: A GMP number resource representing the first integer.
- $num2: A GMP number resource representing the second integer.
Return Values: The gmp_lcm() function returns the lcm of two integers which is provided by the user.
Program 1: The following program demonstrates gmp_lcm() function.
PHP
<?php     // Assuming you have the GMP // extension enabled $a = gmp_init(12); $b = gmp_init(18); $lcm = gmp_lcm($a, $b); echo "LCM of $a and $b is: $lcm\n"; ?> |
Output:
LCM of 12 and 18 is: 36
Program 2: The following program demonstrates gmp_lcm() function.
PHP
<?php   // Assuming you have the GMP // extension enabled $a = gmp_init(12); $b = gmp_init(18); $c = gmp_init(24);   $lcm_of_three = gmp_lcm($a, gmp_lcm($b, $c));   echo "LCM of $a, $b, and $c is: $lcm_of_three\n";   ?> |
Output:
LCM of 12, 18, and 24 is: 72
