2 x 2 x 2 x 3 x 3 x 3 = 216
2 x 2 x 3 x 7 = 84
2 x 2 x 3 = 12, the GCF
It is: 1
It is: 4
It is: 69
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
i believe it's 26 the prime factorization of 156 is 2x2x3x13 and the prime factorization for 910 is 2x5x7x13 and since 2 and 13 are both common you multiply them to get the GCF of 26
At least two or more numbers are needed to find their GCF
That is not what prime factorization is for.
53 is already prime. 2 x 43 = 86 No common prime factors; the GCF is 1.
Prime factorization of 32 = 2x2x2x2x2 Prime factorization of 90 = 2x3x3x5 Prime factorization of 30 = 2x3x5 What is common in the prime factorization of the numbers? Only 2 is common, so GCF is 2.
Whatever you use, you need at least two numbers to find a GCF.
