sally drew a factor tree of a composite number and ended up with 4x4x5x5x3 as the prime factorization.

explain what is wrong with this factorization

1. what is the correct prime factorization?
2. what is the composite number that was factored?

1. Steve

4 is not a prime
2x2x2x2x3x5x5 or 2^4•3•5^2
(usually the primes are listed in increasing order)

2. kel

It always starts from the lowest to the highest 1)the correct factor= 2*2*2*2*3*5*5 (2) 1200 is the composite factor

Could you explain this? ("Dumb it down for me") So far I know that 2^2 x 3 x 5^4 x 8 x 11^2 is equal to 4 x 3 x 625 x 8 x 121. (I think) ========================================== A number is written with the following factorization:
