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
3 is already prime. No factorization.
What is the prime factorization of 256^180
113 is already prime. No factorization.
prime factorization
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 77,2 11,7,2 2 x 7 x 11 = 154
Divide 154 by 2. Divide that result by 7. 2 x 7 x 11 = 154
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
The greatest common factor (GCF) is often also called the greatest common divisor (GCD) or highest common factor (HCF). Keep in mind that these different terms all refer to the same thing: the largest integer which evenly divides two or more numbers.The greatest common factor of 70, 98, and 154 is 14.
