How do I find the factor combinations of the number 2,518,824?

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 2,518,824, 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 2,518,824
-1 -2,518,824

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 2,518,824.

Example:
1 x 2,518,824 = 2,518,824
and
-1 x -2,518,824 = 2,518,824
Notice both answers equal 2,518,824

With that explanation out of the way, let's continue. Next, we take the number 2,518,824 and divide it by 2:

2,518,824 ÷ 2 = 1,259,412

If the quotient is a whole number, then 2 and 1,259,412 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 1,259,412 2,518,824
-1 -2 -1,259,412 -2,518,824

Now, we try dividing 2,518,824 by 3:

2,518,824 ÷ 3 = 839,608

If the quotient is a whole number, then 3 and 839,608 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 3 839,608 1,259,412 2,518,824
-1 -2 -3 -839,608 -1,259,412 -2,518,824

Let's try dividing by 4:

2,518,824 ÷ 4 = 629,706

If the quotient is a whole number, then 4 and 629,706 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 4 629,706 839,608 1,259,412 2,518,824
-1 -2 -3 -4 -629,706 -839,608 -1,259,412 2,518,824
Keep dividing by the next highest number until you cannot divide anymore.

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