Question

how do u do it i don't know because it a long number

Answer 1

Start with the easy questions.

Is 17875 divisible by 2?  No, because 5 is not even.

Is 17875 divisible by 3?  No, because 1+7+8+7+5 = 28, which is not divisible by 3.

Is 17875 divisible by 5?  Yes, because it ends in a 5 or 0.

17875/5 = 3575

3575/5 = 715

715/5 = 143

143 doesn't end in a 0 or 5, so no more 5's.

143 = 11 * 13

17875 = 5 * 5 * 5 * 11 * 13
