How do I find the factor combinations of the number 71,151,744?

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 71,151,744, 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 71,151,744
-1 -71,151,744

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 71,151,744.

Example:
1 x 71,151,744 = 71,151,744
and
-1 x -71,151,744 = 71,151,744
Notice both answers equal 71,151,744

With that explanation out of the way, let's continue. Next, we take the number 71,151,744 and divide it by 2:

71,151,744 ÷ 2 = 35,575,872

If the quotient is a whole number, then 2 and 35,575,872 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 35,575,872 71,151,744
-1 -2 -35,575,872 -71,151,744

Now, we try dividing 71,151,744 by 3:

71,151,744 ÷ 3 = 23,717,248

If the quotient is a whole number, then 3 and 23,717,248 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 23,717,248 35,575,872 71,151,744
-1 -2 -3 -23,717,248 -35,575,872 -71,151,744

Let's try dividing by 4:

71,151,744 ÷ 4 = 17,787,936

If the quotient is a whole number, then 4 and 17,787,936 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 17,787,936 23,717,248 35,575,872 71,151,744
-1 -2 -3 -4 -17,787,936 -23,717,248 -35,575,872 71,151,744
Keep dividing by the next highest number until you cannot divide anymore.

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