How do I find the factor combinations of the number 45,240,524?

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 45,240,524, 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 45,240,524
-1 -45,240,524

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 45,240,524.

Example:
1 x 45,240,524 = 45,240,524
and
-1 x -45,240,524 = 45,240,524
Notice both answers equal 45,240,524

With that explanation out of the way, let's continue. Next, we take the number 45,240,524 and divide it by 2:

45,240,524 ÷ 2 = 22,620,262

If the quotient is a whole number, then 2 and 22,620,262 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 22,620,262 45,240,524
-1 -2 -22,620,262 -45,240,524

Now, we try dividing 45,240,524 by 3:

45,240,524 ÷ 3 = 15,080,174.6667

If the quotient is a whole number, then 3 and 15,080,174.6667 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 22,620,262 45,240,524
-1 -2 -22,620,262 -45,240,524

Let's try dividing by 4:

45,240,524 ÷ 4 = 11,310,131

If the quotient is a whole number, then 4 and 11,310,131 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 4 11,310,131 22,620,262 45,240,524
-1 -2 -4 -11,310,131 -22,620,262 45,240,524
Keep dividing by the next highest number until you cannot divide anymore.

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

124714284998196230,819461,638923,2761,615,7333,231,4666,462,93211,310,13122,620,26245,240,524
