See a solution process below:

Because this is an even number we can divide by $2$ :

$156 = 2 xx 78$

Because 78 is an even number we can also divide it by $2$ "

$156 = 2 xx 2 xx 39$

Because the digits of 39 add up to a number divisible by 3 (3 + 9 = 12) we can divide 39 by $3$ giving:

$156 = 2 xx 2 xx 3 xx 13$

Because these are now all prime numbers the factors of 156 are:

$156 = 2 xx 2 xx 3 xx 13$
