You need at least two numbers to find a GCF. The prime factorization of 207 is 3 x 3 x 23.
3 x 23 = 69 3 x 3 x 23 = 207 3 x 23 = 69, the GCF
It is: 4
It is: 1
It's not necessary. Since 69 is a factor of 207, it is automatically the GCF. But if you insist... 69 3,23 207 3,69 3,3,23 Select the common factors. 3 x 23 = 69, the GCF.
41 is a prime number which makes 41 the gcf of 41 and 82
It is: 4
2 x 2 x 2 x 2 x 2 x 3 = 96 3 x 3 x 23 = 207 The GCF is 3.
At least two or more numbers are needed to find their GCF
That is not what prime factorization is for.
Since 69 is a factor of 207, it will automatically be the GCF of this problem. But let's do it correctly. 3 x 23 = 69 3 x 3 x 23 = 207 Select the common factors. 3 x 23 = 69, the GCF.
53 is already prime. 2 x 43 = 86 No common prime factors; the GCF is 1.
