How do I find the factor combinations of the number 147,070,740?

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 147,070,740, 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.

1 147,070,740
-1 -147,070,740

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 147,070,740.

Example:
1 x 147,070,740 = 147,070,740
and
-1 x -147,070,740 = 147,070,740
Notice both answers equal 147,070,740

With that explanation out of the way, let's continue. Next, we take the number 147,070,740 and divide it by 2:

147,070,740 ÷ 2 = 73,535,370

If the quotient is a whole number, then 2 and 73,535,370 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 73,535,370 147,070,740
-1 -2 -73,535,370 -147,070,740

Now, we try dividing 147,070,740 by 3:

147,070,740 ÷ 3 = 49,023,580

If the quotient is a whole number, then 3 and 49,023,580 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 49,023,580 73,535,370 147,070,740
-1 -2 -3 -49,023,580 -73,535,370 -147,070,740

Let's try dividing by 4:

147,070,740 ÷ 4 = 36,767,685

If the quotient is a whole number, then 4 and 36,767,685 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 36,767,685 49,023,580 73,535,370 147,070,740
-1 -2 -3 -4 -36,767,685 -49,023,580 -73,535,370 147,070,740
Keep dividing by the next highest number until you cannot divide anymore.

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