Answer:

Step-by-step explanation:

455: 5 * 91

455: 5 * 7 * 13

the 5 is easy to find. If some number ends in 5 it is divisible by 5.

91 is not so easy.

91 is not divisible by 2. 91 is an odd number.

It is not divisible by 3. 9 + 1 = 10 which is not divisible by 3

We have already covered 5.  so we start a new series of numbers

91 / 7 = 13 and we are done.
