Using ANY METHOD find the GCF of 30 & 25:
The GCF of 30 & 25 =
2(4x + 5)
The GCF is 3.
You need at least two expressions to find something in common between them. The GCF of 2x and 10 is 2.
you find the GCF (GREATEST COMMON FACTOR) then you divide or multiply you can pick and then you get you simplest from of the fraction
I believe the GCF (Greatest Common Factor) would be 8x I believe the GCF (Greatest Common Factor) would be 8x
42 21,2 7,3,2 You need at least two numbers to find a GCF.
4
To simplify fractions, it is necessary to divide the numerator and the denominator by their GCF. You can find their GCF by comparing their prime factorizations. You can find their prime factorizations through the use of factor trees.
279,33,3,34515,35,3,33 x 3 = 9, the GCF
1
142,7282,142,2,72 x 7 = 14, the GCF
The factors of 48 are 1,2,3,4,6,8,12,16,24 and 48. You need another set of factors to compare them with to find a GCF.
You need at least two factor trees to find a GCF.
9 3,3 18 6,3 2,3,3 The GCF is 9.
You Do a Factor Tree which is very simple. But the answer is 12
The factor tree is just a way to display the prime factorization. Once you have that, you can find the GCF. Example: 30 and 42 2 x 3 x 5 = 30 2 x 3 x 7 = 42 Select the common factors. 2 x 3 = 6, the GCF.
2 is a prime number, it doesn't have a factor tree. You can save time and effort by remembering that if the smaller of a pair of numbers is a factor of the larger one, it is automatically the GCF. The GCF of 2 and 36 is 2.
