Question

Use prime factorizations to find each GCF. 12r3, 8r

Answer 1

Is that

\[12r ^{3}, 8r\]

?

Answer 2

yes

Answer 3

Ok. So to determine the GCF, let's try writing out the prime factorization of 12 and the prime factorization of 8. We can already see that \[r ^{3}\] and \[r \] have a greatest common factor of r.

Answer 4

ok.

Answer 5

"Prime factors of positive integers are found by using the primes in order as divisors. The prime factorization of a positive integer is the expression of the integer as a product of prime factors."

Answer 6

ok that helps a lot better thanks.
