How do I find the factor combinations of the number 70,255,476?

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 70,255,476, 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 70,255,476
-1 -70,255,476

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 70,255,476.

Example:
1 x 70,255,476 = 70,255,476
and
-1 x -70,255,476 = 70,255,476
Notice both answers equal 70,255,476

With that explanation out of the way, let's continue. Next, we take the number 70,255,476 and divide it by 2:

70,255,476 ÷ 2 = 35,127,738

If the quotient is a whole number, then 2 and 35,127,738 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 35,127,738 70,255,476
-1 -2 -35,127,738 -70,255,476

Now, we try dividing 70,255,476 by 3:

70,255,476 ÷ 3 = 23,418,492

If the quotient is a whole number, then 3 and 23,418,492 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 23,418,492 35,127,738 70,255,476
-1 -2 -3 -23,418,492 -35,127,738 -70,255,476

Let's try dividing by 4:

70,255,476 ÷ 4 = 17,563,869

If the quotient is a whole number, then 4 and 17,563,869 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 17,563,869 23,418,492 35,127,738 70,255,476
-1 -2 -3 -4 -17,563,869 -23,418,492 -35,127,738 70,255,476
Keep dividing by the next highest number until you cannot divide anymore.

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