If that's 12 and 25, they have no common prime factors, so the GCF is 1.

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.

12 = 22 x 31

22*3 = 12

They are: 12 and 360 respectively

The factors of 12 are: 1,2,3,4,6. The prime factors are the prime numbers in the factors. So: 1,2,3 are the prime factors of 12.

The GCF of 12 and 20 is 4.The factors of 12 are 1, 2, 3, 4, 6, and 12. The factors of 20 are 1, 2, 4, 5, 10, and 20.The factors they have in common are 1, 2, and 4. Therefore, 4 is the greatest common factor.The greatest common factor can also be determined from the prime factors by multiplying the common prime factors together.The prime factors of 12 are 2, 2, and 3.The prime factors of 20 are 2, 2, and 5.The common prime factors are 2 and 2, so the greatest common factor is 2 x 2 = 4.The greatest common factor of 12 and 20 is 4

To find the greatest common factor (GCF), first find the prime factorization of the two numbers. The GCF is the product of all of the prime factors the two numbers have in common. If two numbers have no common factors, the GCF is 1. (Since all numbers are divisible by 1.) Example: Find the GCF of 60 and 24. Prime factors of 60: 2, 2, 3, 5 Prime factors of 24: 2, 2, 2, 3 Common factors: 2, 2, 3 GCF: 2x2x3=12 Example: Find the GCF of 17 and 21. Prime factors of 17: 17 Prime factors of 21: 3, 7 Common factors: None (1). GCF: 1

The GCF of 84 and 156 is 12.First, find the prime factors:84 = 2*2*3*7156 = 2*2*3*13Then, to determine the gcf, multiply the shared prime factors:GCF = 2*2*3 = 12

The GCF of 24 and 12 is 12.

Divide them by prime numbers until all the factors are prime. 3 is already prime. The prime factorization of 6 is 2 x 3. The prime factorization of 12 is 2 x 2 x 3. If you're looking for the GCF, select the common factors. The GCF is 3. If you're looking for the LCM, combine the factors, eliminating duplicates. 2 x 2 x 3 = 12, the LCM.

The prime factors of 12 are: 2 and 3.

The GCF of 120 and 156 is 12.The prime factors of 120 are 2·2·2·3·5The prime factors of 156 are 2·2·3·13The shared prime factors are 2·2·3The unshared factors are 2, 5, and 13Consequently the highest common factor will be 2·2·3 = 12120 = 12*10156 = 12*1310 and 13 share no common factors (except 1 of course)The GCF is 12.

The prime factors of 6 are: 2 and 3.The prime factors of 12 are: 2 and 3.

Yes, 12 has prime factors. The prime factors of 12 are 2, 2, and 3, so the distinct prime factors are 2 and 3. Almost all integers have prime factors. The integers without prime factors are -1, 0, and 1.

The GCF of 12, 24, and 32 is 4 Prime factors of 12: 2 x 3 x 2 Prime factors of 24: 3 x 2 x 2 x 2 Prime factors of 32: 2 x 2 x 2 x 2 x 2 The common prime factors of all three numbers are 2 x 2. Therefore, the GCF of 12, 24 and 32 is 2 x 2 = 4
