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
