GFC of 20x - 4
To find the greatest common factor (GCF) of 20x and 4, we need to find the largest value that can divide evenly into both 20x and 4.
First, let's factor out the common factors of 20x and 4.
20x = 2 * 2 * 5 * x
4 = 2 * 2
The common factors are 2 * 2 = 4.
Therefore, the GCF of 20x and 4 is 4.
Find the GFC of 30m + 12n
To find the greatest common factor (GCF) of 30m and 12n, we need to find the largest value that can divide evenly into both 30m and 12n.
First, let's factor out the common factors of 30m and 12n.
30m = 2 * 3 * 5 * m
12n = 2 * 2 * 3 * n
The common factors are 2 * 3 = 6.
Therefore, the GCF of 30m and 12n is 6.
