# Can a greatest common factor be 1?

It is easily possible to have only 1 as a common factor.

Other than one, numbers like 24 and 35 have nothing in common.

The following are their primary factors:

The HCF in this scenario would be 1.

Every number has a factor of 1.

Yes, the greatest common factor (GCF) of two numbers can be 1. This occurs when the numbers do not share any common factors other than 1. In other words, if the only positive integer that divides both numbers evenly is 1, then the GCF of those numbers is 1. This often happens when the numbers are relatively prime, meaning they have no common factors other than 1. For example, the GCF of 6 and 7 is 1, as the only positive integer that divides both 6 and 7 evenly is 1. Similarly, the GCF of 15 and 28 is also 1, as 15 and 28 do not share any common factors other than 1.

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.
