How do I find the factor combinations of the number 21,607,465?

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 21,607,465, 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 21,607,465
-1 -21,607,465

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 21,607,465.

Example:
1 x 21,607,465 = 21,607,465
and
-1 x -21,607,465 = 21,607,465
Notice both answers equal 21,607,465

With that explanation out of the way, let's continue. Next, we take the number 21,607,465 and divide it by 2:

21,607,465 ÷ 2 = 10,803,732.5

If the quotient is a whole number, then 2 and 10,803,732.5 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 21,607,465
-1 -21,607,465

Now, we try dividing 21,607,465 by 3:

21,607,465 ÷ 3 = 7,202,488.3333

If the quotient is a whole number, then 3 and 7,202,488.3333 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 21,607,465
-1 -21,607,465

Let's try dividing by 4:

21,607,465 ÷ 4 = 5,401,866.25

If the quotient is a whole number, then 4 and 5,401,866.25 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 21,607,465
-1 21,607,465
Keep dividing by the next highest number until you cannot divide anymore.

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