I need help finding the GCD and LCM of the following using the prime factorization method and I have no clue!! a. 11 and 19 b. 140 and 320 c. 800, 75, and 450 d. 104 and 320

OpenStudy (sandra):

ok so prime factorization = find the prime numbers that multiply together to make the original number

OpenStudy (sandra):

a. 1 and 1, since there are no prime numbers that divide into 11 and 19 (in fact those are also prime)
