2 x 43 = 86 2 x 7 x 11 = 154 The GCF is 2.
It is: 4
It is: 1
That is not what prime factorization is for.
Whatever you use, you need at least two numbers to find a GCF.
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.
2 x 43 = 86 2 x 7 x 11 = 154 The GCF is 2.
2 x 2 x 2 x 7 = 562 x 7 x 11 = 1542 x 7 = 14, the GCF
It is: 4
It is: 1
It is: 69
2 x 43 = 862 x 7 x 11 = 154The GCF is 2.
You need at least two numbers to find a GCF. The prime factorization of 207 is 3 x 3 x 23.
41 is a prime number which makes 41 the gcf of 41 and 82
It is: 4
At least two or more numbers are needed to find their GCF
That is not what prime factorization is for.
