How do I find the factor combinations of the number 7,202,459?

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 7,202,459, 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 7,202,459
-1 -7,202,459

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 7,202,459.

Example:
1 x 7,202,459 = 7,202,459
and
-1 x -7,202,459 = 7,202,459
Notice both answers equal 7,202,459

With that explanation out of the way, let's continue. Next, we take the number 7,202,459 and divide it by 2:

7,202,459 ÷ 2 = 3,601,229.5

If the quotient is a whole number, then 2 and 3,601,229.5 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 7,202,459
-1 -7,202,459

Now, we try dividing 7,202,459 by 3:

7,202,459 ÷ 3 = 2,400,819.6667

If the quotient is a whole number, then 3 and 2,400,819.6667 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 7,202,459
-1 -7,202,459

Let's try dividing by 4:

7,202,459 ÷ 4 = 1,800,614.75

If the quotient is a whole number, then 4 and 1,800,614.75 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 7,202,459
-1 7,202,459
Keep dividing by the next highest number until you cannot divide anymore.

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

1115631,1636,19312,793654,7697,202,459
-1-11-563-1,163-6,193-12,793-654,769-7,202,459
