    Is that \[12r ^{3}, 8r\] ?

    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.

    "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."
