# Is 1 a Factor of 9?

In this article we are going to check whether 1 is a factor of 9 and explain the two easiest methods to calculate this for yourself.

What we can do is list out all of the factors of 9 and then check the resulting list to see if 1 is one of those numbers. Here are all the factors of 9:

• 1
• 3
• 9

We can also list the factors of 9 into a comma separated list as well:

1, 3, and 9

We are checking to see if the number 1 is in this list and we can clearly see that it is in the list of factors for 9.

This means, 1 is a factor of 9.

We can also check whether 1 is a factor of 9 by simplying dividing 9 by 1 to see if the quotient (the resulting answer) is a whole or a fractional number.

If the result is a whole number, then we know that 1 is a factor of 9.

If the result is a fractional number, then we know that 1 is not a factor of 9.

9 divided by 1 is 9 which is a whole number. This confirms our answer from the factor list method above that 1 is a factor of 9.

Hopefully this has not only answered the question "is 1 a factor of 9?", but also explained the methods for working this out for yourself.

Challenge yourself to try and calculate whether one number is a factor of another using both of the methods above to practice your new understanding of factors.
