How do I find the factor combinations of the number 277,266,780?

Unfortunately, there's not simple formula to identifying all of the factors of a number and it can be a tedious process when trying to identify the divisors of larger numbers. To find the factor combinations of the number 277,266,780, it is easier to work with a table - it's called factoring from the outside in.

Outside in Factoring

We start by creating a table and writing 1 on the left side and then the number we're trying to find the factors for on the right side in a table. Then, below that, write the numbers as a negative as well.

1 277,266,780
-1 -277,266,780

Why are the negative numbers included?

When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 277,266,780.

Example:
1 x 277,266,780 = 277,266,780
and
-1 x -277,266,780 = 277,266,780
Notice both answers equal 277,266,780

With that explanation out of the way, let's continue. Next, we take the number 277,266,780 and divide it by 2:

277,266,780 ÷ 2 = 138,633,390

If the quotient is a whole number, then 2 and 138,633,390 are factors. In this case, the quotient is a whole number. Write them in the table inside the other two factors like the below example. Don't forget to write the negative numbers too!

Here is what our table should look like at this step:

1 2 138,633,390 277,266,780
-1 -2 -138,633,390 -277,266,780

Now, we try dividing 277,266,780 by 3:

277,266,780 ÷ 3 = 92,422,260

If the quotient is a whole number, then 3 and 92,422,260 are factors. In this case, the quotient is a whole number. Write them in the table inside the other two factors like the below example. Don't forget to write the negative numbers too!

Here is what our table should look like at this step:

1 2 3 92,422,260 138,633,390 277,266,780
-1 -2 -3 -92,422,260 -138,633,390 -277,266,780

Let's try dividing by 4:

277,266,780 ÷ 4 = 69,316,695

If the quotient is a whole number, then 4 and 69,316,695 are factors. In this case, the quotient is a whole number. Write them in the table inside the other two factors like the below example. Don't forget to write the negative numbers too!

Here is what our table should look like at this step:

1 2 3 4 69,316,695 92,422,260 138,633,390 277,266,780
-1 -2 -3 -4 -69,316,695 -92,422,260 -138,633,390 277,266,780
Keep dividing by the next highest number until you cannot divide anymore.

If you did it right, you will end up with this table:
