How do I find the factor combinations of the number 7,994,357?

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 7,994,357, 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 7,994,357
-1 -7,994,357

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 7,994,357.

Example:
1 x 7,994,357 = 7,994,357
and
-1 x -7,994,357 = 7,994,357
Notice both answers equal 7,994,357

With that explanation out of the way, let's continue. Next, we take the number 7,994,357 and divide it by 2:

7,994,357 ÷ 2 = 3,997,178.5

If the quotient is a whole number, then 2 and 3,997,178.5 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 7,994,357
-1 -7,994,357

Now, we try dividing 7,994,357 by 3:

7,994,357 ÷ 3 = 2,664,785.6667

If the quotient is a whole number, then 3 and 2,664,785.6667 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 7,994,357
-1 -7,994,357

Let's try dividing by 4:

7,994,357 ÷ 4 = 1,998,589.25

If the quotient is a whole number, then 4 and 1,998,589.25 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 7,994,357
-1 7,994,357
Keep dividing by the next highest number until you cannot divide anymore.

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

175412,1113,78714,7771,142,0517,994,357
