What are the factors of 156?

Answer 1

Autumn Arnold

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#

The factors of 156 are as follows since they are now all prime numbers:

#156 = 2 xx 2 xx 3 xx 13#
