2 & 7
That appears to be a little backwards. It makes more sense to find the GCF of 56 and 154 using prime factorization. 2 x 2 x 2 x 7 = 56 2 x 7 x 11 = 154 2 x 7 = 14, the GCF
The prime factorization of 56 is:7 x 23 = 56
2 x 2 x 2 x 7 = 56 2 x 7 x 11 = 154 2 x 7 = 14, the GCF
It is: 21*71*111 = 154
56 is 8*7
The prime factorization of 18 is 2 x 3 x 3. The prime factorization of 56 is 2 x 2 x 2 x7.
Use a factor tree. 154 77,2 11,7,2
2 x 2 x 2 x 7 = 56 2 x 7 x 11 = 154 2 x 7 = 14, the GCF
the prime facotrization of 154 is 12 times 3 times 5
56 prime factorization 2*2*2*7 exponents: 23*7 * = multiply
154 = 11 x 7 x 2
56 and 44
