How do I find the factor combinations of the number 1,825,644?

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 1,825,644, 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 1,825,644
-1 -1,825,644

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 1,825,644.

Example:
1 x 1,825,644 = 1,825,644
and
-1 x -1,825,644 = 1,825,644
Notice both answers equal 1,825,644

With that explanation out of the way, let's continue. Next, we take the number 1,825,644 and divide it by 2:

1,825,644 ÷ 2 = 912,822

If the quotient is a whole number, then 2 and 912,822 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 2 912,822 1,825,644
-1 -2 -912,822 -1,825,644

Now, we try dividing 1,825,644 by 3:

1,825,644 ÷ 3 = 608,548

If the quotient is a whole number, then 3 and 608,548 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 3 608,548 912,822 1,825,644
-1 -2 -3 -608,548 -912,822 -1,825,644

Let's try dividing by 4:

1,825,644 ÷ 4 = 456,411

If the quotient is a whole number, then 4 and 456,411 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 4 456,411 608,548 912,822 1,825,644
-1 -2 -3 -4 -456,411 -608,548 -912,822 1,825,644
Keep dividing by the next highest number until you cannot divide anymore.

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