How do I find the factor combinations of the number 7,022,825?

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 7,022,825, 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 7,022,825
-1 -7,022,825

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 7,022,825.

Example:
1 x 7,022,825 = 7,022,825
and
-1 x -7,022,825 = 7,022,825
Notice both answers equal 7,022,825

With that explanation out of the way, let's continue. Next, we take the number 7,022,825 and divide it by 2:

7,022,825 ÷ 2 = 3,511,412.5

If the quotient is a whole number, then 2 and 3,511,412.5 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 7,022,825
-1 -7,022,825

Now, we try dividing 7,022,825 by 3:

7,022,825 ÷ 3 = 2,340,941.6667

If the quotient is a whole number, then 3 and 2,340,941.6667 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 7,022,825
-1 -7,022,825

Let's try dividing by 4:

7,022,825 ÷ 4 = 1,755,706.25

If the quotient is a whole number, then 4 and 1,755,706.25 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 7,022,825
-1 7,022,825
Keep dividing by the next highest number until you cannot divide anymore.

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

1525280,9131,404,5657,022,825
-1-5-25-280,913-1,404,565-7,022,825
