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.
To find the greatest common factor (GCF) of 136, 102, and 51, we first need to factorize each number. The prime factorization of 136 is 2^3 * 17, the prime factorization of 102 is 2 * 3 * 17, and the prime factorization of 51 is 3 * 17. To find the GCF, we need to identify the common prime factors among the numbers, which are 17 and 1. Therefore, the GCF of 136, 102, and 51 is 17.
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.
