3 x 3 x 11 = 99
3 x 5 x 11 = 165
3 x 11 = 33, the GCF
It is: 1
It is: 4
That is not what prime factorization is for.
Whatever you use, you need at least two numbers to find a GCF.
Prime factorization of 288 = 2x2x2x2x2x3x3Prime factorization of 40 = 2x2x2x5Prime factorization of 24 = 2x2x2x32x2x2 = 8, the GCF
55 3*55 = 165 2*55 = 110
Their gcf is just 1
It is: 69
It is: 1
It is: 4
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.
The greatest common factor of 165 and 180 is 5. The prime factorization of 165 is 11*3*5. The prime factors of 180 are 2*2*5*9.
53 is already prime. 2 x 43 = 86 No common prime factors; the GCF is 1.
