226 is even, hence divisible by 2. 226 divided by 2 is 113

113 is not even, so not divisible by 2.

113 sum of the digits is 5. 5 is not divisible by 3, so 113 is not divisible by 3.

113 does not have 0 or 5 as a units digit. 113 is not divisible by 5.

113 is not divisible by 7. (7 X 16 = 112)

113 is not divisible by 11. (11 X 10 = 110, 11 X 11 = 121)

11 squared is 121 which is greater than 113. Therefore 113 is prime.

226 = 2 X 113.
