# Is 1 a Factor of 378?

In this article we are going to check whether 1 is a factor of 378 and explain the two easiest methods to calculate this for yourself.

What we can do is list out all of the factors of 378 and then check the resulting list to see if 1 is one of those numbers. Here are all the factors of 378:

• 1
• 2
• 3
• 6
• 7
• 9
• 14
• 18
• 21
• 27
• 42
• 54
• 63
• 126
• 189
• 378

We can also list the factors of 378 into a comma separated list as well:

1, 2, 3, 6, 7, 9, 14, 18, 21, 27, 42, 54, 63, 126, 189, and 378

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 378.

This means, 1 is a factor of 378.

We can also check whether 1 is a factor of 378 by simplying dividing 378 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 378.

If the result is a fractional number, then we know that 1 is not a factor of 378.

378 divided by 1 is 378 which is a whole number. This confirms our answer from the factor list method above that 1 is a factor of 378.

Hopefully this has not only answered the question "is 1 a factor of 378?", 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.
