all divisors must have the same list of primes, with powers the same or less.
(b) does not work, since the dividend does not include a 5.
so, what is your answer?
Without using a calculator, decide which of these numbers divide into 2^5 * 3^9 * 7^2 * 13^5 8 17^4 * 19 with no remainder. Explain how you know.
a) 2^4 * 3^8 * 7^2 * 13^4 * 17^4 *
b) 2^5 * 3^2 * 5 * 7^2* 17
c) 2^4 * 13^4 * 17^4 * 19^4
d) 2^2 * 3^5 * 7 * 13^3 * 17^2 * 19

I don't really understand that, doesn't b have a five in there?
yes, but b is the divisor
For it to divide the big number above (the dividend), there must also be a 5 there.

Ohhhh! Thank you!
I still dont get it. Can you explain the answer a bit more detailed?
