Answer:
Gabrielle: What Gabrielle did was use a factor tree to factor out the prime numbers. 64=8*8, then Gabrielle found the factors for 8, 2 and 4. And 2 is prime so now Gabrielle will factor 4 which is 2 and 2. 2 is prime so he stopped there. Then he multiplied all of the prime numbers to get 64
John:
What John did was find factors for 64 with at least one prime number. 2 is prime so he did 2*32, left the two there and factored out 32 using a prime number which was to. 2*2*16, factor out sixteen, 2*2*2*8 then factor out 8. 2*2*2*2*4, factor out 4, 2*2*2*2*2
