If you are talking of 20 and 24 then factor both to prime factors. 20=2x2x5 24=2x2x2x3 circle the common ones. 2x2=4 the greatest common factor.
2x2-x-6 = (2x+3)(x-2)
the prime factorization of 32 is 2x2x2x2x2 and the factor tree is 32 8 4 2x4 2x2 2x2
4x4 + 1 = (2x2 - 2x + 1)(2x2 + 2x + 1)
2x2+13x+15 = (2x+3)(x+5)
Show the terms as additive here..., 8X2 + 10X3 factor out 2X2 2X2(4 + 5X) ---------------- 2X2 ==== greatest common factor
2x2 (i.e. 4)
Select the common factors. 2 x 2 = 4, the GCF.

Prime factor each number. Circle all the prime common factors then, multiply them 28=2x2x7 32=2x2x2x2x2 GCF=2x2=4
4; the prime factorization of 24= 2x2x2x3, 44=2x2x11, 52=2x2x13. the factors that they have in common are 2x2=4 or 4; the factors of 24 are 1,2,3,4,6,8,12,24. 44 are 1,2,4,11,22,44. 52 are 1,2,4,13,26,52. the greatest factor that they all have in common is 4.
The GDF is 2x2 =4
Answer: 4Definition: A factor is a divisor - a number that will evenly divide into another number. The greatest common factor of two or more numbers is the largest factor that the numbers have in common.Method:One way to determine the common factors and greatest common factor is to find all the factors of the numbers and compare them.The factors of 12 are 1, 2, 3, 4, 6, and 12.The factors of 100 are 1, 2, 4, 5, 10, 20, 25, 50, and 100.The common factors are 1, 2, and 4. Therefore, the greatest common factor is 4.
If that's +28, the answer is (x - 4)
16=2x2x2x220=2x2x5GCF=2x2=4
The greatest common factor of 12, 28, and 40 is 4 To find the greatest common factor of numbers, you first need to split these numbers into their prime factors: 12 = 2x2x3 28 = 2x2x7 40 = 2x2x2x2x5 You then need to find which prime factors are shared between the numbers. In this case, each of the numbers uses two 2s, but no other numbers are common between them. So to find the GCF we simply multiply two 2s: 2x2=4 Thus the GCF of 12, 28 and 40 is 4.
