2 x 2 x 3 = 12
3 x 5 = 15
Select the common factor.
The GCF is 3.
They are: 12 and 360 respectively
22*3 = 12
The prime factorization for 12 is 2 x 2 x 3The prime factorization for 20 is 2 x 2 x 5GCF of (12,20) = 4
The GCF of 12 and 54 is 6. To find the GCF, write the prime factorizations of each number.The prime factorization of 12 is 2*2*3The prime factorization of 54 is 2*3*3*3The factors in common are 2*3 = 6, so that is the GCF.
The GCF of 12 and 75 is 3.The prime factorization of 12 is 2*2*3.The prime factorization of 75 is 3*5*5Their greatest common factor is 3.
2 x 2 x 3 = 12 3 x 5 = 15 The GCF is 3.
The GCF of 12, 24, and 39 is 3.The prime factorization of 12 is 2*2*3The prime factorization of 24 is 2*2*2*3The prime factorization of 39 is 3*13So the GCF of 12, 24, and 39 is 3.
YES. Prime factorization can be used to get the GCF.Example:Prime factorization of:12 = 2 x 2 x 324 = 2 x 2 x 3 x 2============GCF=2 x 2 x 3GCF=12
The GCF is 2. The prime factorization of 18 is 2x3x3 and the prime factorization of 16 is 2x2x2x2. They both have one 2 in common so that would be the greatest common factor.
the prime factorization of 12 in exponents is 2 to the second power times 3
2 x 2 x 3 = 12 2 x 2 x 2 x 2 = 16 2 x 2 = 4, the GCF
You need at least two numbers to find a GCF.
