3 x 3 x 5 = 45
2 x 2 x 2 x 7 = 56
No common prime factors. The GCF is 1.
You need at least two numbers to find a GCF. The prime factorization of 207 is 3 x 3 x 23.
The prime factorization of 9 is 32 You need at least two numbers to find a GCF.
At least two or more numbers are needed to find their GCF
Whatever you use, you need at least two numbers to find a GCF.
You can find the GCF and/or the LCM of a set of numbers by comparing the prime factorizations of the individual members of the set.
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.
You need at least two numbers to find a GCF, whichever method you use.
