154 = 11 x 7 x 2
4
7 x 11 x 2
23 is already prime.
all the numbers are prime numbers therefore the prime factorization of 2*2*5*11=2*2*5*11
154 77,2 11,7,2 2 x 7 x 11 = 154
It is: 21*71*111 = 154
2 & 7
Use a factor tree. 154 77,2 11,7,2
the prime facotrization of 154 is 12 times 3 times 5
154 = 11 x 7 x 2
4
The GCF of 86 and 154 is 2. 86=2x43 154 = 2x7x11 Now the GCF is 2 since 43 does not occur in the prime factorization of 154 and 7 and 11 do not appear in the prime factorization of 86.
154 = 2 x 7 x 11
7 x 11 x 2
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
23 is already prime.
