# PHP program to find the first natural number whose factorial can be divided by a number ‘x’

To find the first natural number whose factorial can be divided by a number ‘x’, the code is as follows −

## Example

<?php function factorial_num($x_val) { $i = 1; $fact_num = 4; for ($i = 1; $i < $x_val; $i++) { $fact_num = $fact_num * $i; if ($fact_num % $x_val == 0) break; } return $i; } $x_val = 16; print_r("The first natural number whose factorial can be divided by 16 is "); echo(factorial_num($x_val)); ?>

## Output

The first natural number whose factorial can be divided by 16 is 4

A function named ‘factorial_num’ computes factorial of a number and checks to see if it is divisible by 16, and if yes, returns that number as output. Outside the function, a number is defined and it is passed as parameter to the function. Relevant output is displayed on the console.
