Example: 30 and 42
The factors of 30 are:
1, 2, 3, 5, 6, 10, 15, 30
The factors of 42 are:
1, 2, 3, 6, 7, 14, 21, 42
The common factors are:
1, 2, 3, 6
The Greatest Common Factor:
GCF = 6
Using a division ladder haw do i find the gcf
By finding their common prime numbers.
Whatever you use, you need at least two numbers to find a GCF.
listing method , factor tree
If you have two numbers, multiply them together and divide that total by the GCF. The result will be the LCM.
Example: 30 and 42 1,2,3,5,6,10,15,30 1,2,3,6,7,14,21,42 The GCF is 6.
To find the GCF or the LCM of a set of numbers, it is sometimes practical to write out lists of the factors or multiples as the case may be and compare them. This is known as the listing method.

Using ANY METHOD find the GCF of 30 & 25: The GCF of 30 & 25 =
The division ladder is a method used to find the greatest common factor (GCF) of two numbers by listing the factors of each number. To find the GCF of 82, you would start by factoring the number 82. The factors of 82 are 1, 2, 41, and 82. Therefore, the GCF of 82 is 1.
By finding their common prime numbers.
At least two or more numbers are needed to find their GCF
Whatever you use, you need at least two numbers to find a GCF.
