How do I find the factor combinations of the number 1,797,497?

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 1,797,497, 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 1,797,497
-1 -1,797,497

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 1,797,497.

Example:
1 x 1,797,497 = 1,797,497
and
-1 x -1,797,497 = 1,797,497
Notice both answers equal 1,797,497

With that explanation out of the way, let's continue. Next, we take the number 1,797,497 and divide it by 2:

1,797,497 ÷ 2 = 898,748.5

If the quotient is a whole number, then 2 and 898,748.5 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 1,797,497
-1 -1,797,497

Now, we try dividing 1,797,497 by 3:

1,797,497 ÷ 3 = 599,165.6667

If the quotient is a whole number, then 3 and 599,165.6667 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 1,797,497
-1 -1,797,497

Let's try dividing by 4:

1,797,497 ÷ 4 = 449,374.25

If the quotient is a whole number, then 4 and 449,374.25 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 1,797,497
-1 1,797,497
Keep dividing by the next highest number until you cannot divide anymore.

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