How do I find the factor combinations of the number 162,644,544?

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 162,644,544, 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.

1 162,644,544
-1 -162,644,544

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 162,644,544.

Example:
1 x 162,644,544 = 162,644,544
and
-1 x -162,644,544 = 162,644,544
Notice both answers equal 162,644,544

With that explanation out of the way, let's continue. Next, we take the number 162,644,544 and divide it by 2:

162,644,544 ÷ 2 = 81,322,272

If the quotient is a whole number, then 2 and 81,322,272 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 81,322,272 162,644,544
-1 -2 -81,322,272 -162,644,544

Now, we try dividing 162,644,544 by 3:

162,644,544 ÷ 3 = 54,214,848

If the quotient is a whole number, then 3 and 54,214,848 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 54,214,848 81,322,272 162,644,544
-1 -2 -3 -54,214,848 -81,322,272 -162,644,544

Let's try dividing by 4:

162,644,544 ÷ 4 = 40,661,136

If the quotient is a whole number, then 4 and 40,661,136 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 40,661,136 54,214,848 81,322,272 162,644,544
-1 -2 -3 -4 -40,661,136 -54,214,848 -81,322,272 162,644,544
Keep dividing by the next highest number until you cannot divide anymore.

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