How do I find the factor combinations of the number 160,855,938?

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 160,855,938, 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.

1 160,855,938
-1 -160,855,938

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 160,855,938.

Example:
1 x 160,855,938 = 160,855,938
and
-1 x -160,855,938 = 160,855,938
Notice both answers equal 160,855,938

With that explanation out of the way, let's continue. Next, we take the number 160,855,938 and divide it by 2:

160,855,938 ÷ 2 = 80,427,969

If the quotient is a whole number, then 2 and 80,427,969 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 80,427,969 160,855,938
-1 -2 -80,427,969 -160,855,938

Now, we try dividing 160,855,938 by 3:

160,855,938 ÷ 3 = 53,618,646

If the quotient is a whole number, then 3 and 53,618,646 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 53,618,646 80,427,969 160,855,938
-1 -2 -3 -53,618,646 -80,427,969 -160,855,938

Let's try dividing by 4:

160,855,938 ÷ 4 = 40,213,984.5

If the quotient is a whole number, then 4 and 40,213,984.5 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.

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

1 2 3 53,618,646 80,427,969 160,855,938
-1 -2 -3 -53,618,646 -80,427,969 160,855,938
Keep dividing by the next highest number until you cannot divide anymore.

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