# How do you find the GCF of 20 and 30?

The preferred technique is to factor each number then multiply all common factors together to find the greatest common factor.

Down to its prime factors, factor 20 comes first.

Factor 30 is reduced to its primary factors.

Two and five are the shared factors.

Shortcuts do exist that frequently function, though

Then, it is easy to see that 10 is the most significant common factor.

To find the greatest common factor (GCF) of 20 and 30, identify the common factors of both numbers. The common factors of 20 are 1, 2, 4, 5, 10, and 20. The common factors of 30 are 1, 2, 3, 5, 6, 10, 15, and 30. The largest number that appears in both lists is 10, so the GCF of 20 and 30 is 10.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
