gcf(30, 42) = 6.
30 = 2 x 3 x 5
42 = 2 x 3 x 7
hcf = 2 x 3 = 6
Using ANY METHOD find the GCF of 30 & 25: The GCF of 30 & 25 =
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.
Since 5 is a factor of 30, it is automatically the GCF.
Since 3 is a factor of 30, it is automatically the GCF.
The GCF of 30 and 90 is 30.
The Greatest Common Factor (GCF) of 57 and 30 is 3.
The Greatest Common Factor (GCF) of 30 and 204 is 6.
The GCF is 30.
The GCF of 3 and 30 is 3.3.
The GCF is 30.
Since 15 is a factor of 45, it is automatically the GCF.
Factor trees are ways of finding the prime factorization of given numbers. Example: 30 and 42 30 15,2 5,3,2 42 21,2 7,3,2 Select the common factors. 2 x 3 = 6, the GCF.
