Prime factors of 12: 2*2*3
Prme factors of 77: 7*11
Therefore the GCF is 1
It is: 4
It is: 1
That is not what prime factorization is for.
Whatever you use, you need at least two numbers to find a GCF.
2 x 3 x 13 = 78 2 x 2 x 2 x 13 = 104 2 x 13 = 26, the GCF
To find the greatest common factor (GCF) of 56, 64, and 104, we first need to find the prime factorization of each number. The prime factorization of 56 is 2^3 * 7, the prime factorization of 64 is 2^6, and the prime factorization of 104 is 2^3 * 13. To find the GCF, we look for the highest power of common prime factors in all the numbers, which is 2^3. Therefore, the greatest common factor for 56, 64, and 104 is 8.
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
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.
