How do I find the factor combinations of the number 2,457,469?

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 2,457,469, 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 2,457,469
-1 -2,457,469

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 2,457,469.

Example:
1 x 2,457,469 = 2,457,469
and
-1 x -2,457,469 = 2,457,469
Notice both answers equal 2,457,469

With that explanation out of the way, let's continue. Next, we take the number 2,457,469 and divide it by 2:

2,457,469 ÷ 2 = 1,228,734.5

If the quotient is a whole number, then 2 and 1,228,734.5 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 2,457,469
-1 -2,457,469

Now, we try dividing 2,457,469 by 3:

2,457,469 ÷ 3 = 819,156.3333

If the quotient is a whole number, then 3 and 819,156.3333 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 2,457,469
-1 -2,457,469

Let's try dividing by 4:

2,457,469 ÷ 4 = 614,367.25

If the quotient is a whole number, then 4 and 614,367.25 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 2,457,469
-1 2,457,469
Keep dividing by the next highest number until you cannot divide anymore.

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

17171071191937491,3511,8193,28112,73320,65122,967144,557351,0672,457,469
