I see how to do those but,instead of doing all that adding I am doing is as to see what prime factor goes into each number then multiplying them all together. Gisele
The prime factorization of 88 is 2x11 The prime factorization of 90 is 2 x 3 x 5 The primefactorization of 91 is 7 x 13
Can you do the rest?
