How do I find the factor combinations of the number 1,457,988?

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 1,457,988, 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 1,457,988
-1 -1,457,988

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 1,457,988.

Example:
1 x 1,457,988 = 1,457,988
and
-1 x -1,457,988 = 1,457,988
Notice both answers equal 1,457,988

With that explanation out of the way, let's continue. Next, we take the number 1,457,988 and divide it by 2:

1,457,988 ÷ 2 = 728,994

If the quotient is a whole number, then 2 and 728,994 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 2 728,994 1,457,988
-1 -2 -728,994 -1,457,988

Now, we try dividing 1,457,988 by 3:

1,457,988 ÷ 3 = 485,996

If the quotient is a whole number, then 3 and 485,996 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 3 485,996 728,994 1,457,988
-1 -2 -3 -485,996 -728,994 -1,457,988

Let's try dividing by 4:

1,457,988 ÷ 4 = 364,497

If the quotient is a whole number, then 4 and 364,497 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 4 364,497 485,996 728,994 1,457,988
-1 -2 -3 -4 -364,497 -485,996 -728,994 1,457,988
Keep dividing by the next highest number until you cannot divide anymore.

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