all the numbers are prime numbers therefore the prime factorization of 2*2*5*11=2*2*5*11

That's a lot of extra work for this problem but here goes. 3 is already prime so it doesn't really have a factor tree or prime factorization. The prime factorization of 4 is 2 x 2 which looks like this in a factor tree.42,23 and 4 have no common prime factors, so the LCM is their product, 12

7,700 = 22 × 52 × 7 × 11 to find it you can make a factor tree. Start with dividing the number by 2 and then again by 2. Next try 3, it does not work, so try 5 and then again. Keep going and you will have a factor tree that gives you the prime factorization.

13 is already prime. Just write it down.
