How do I find the factor combinations of the number 9,774,481?

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 9,774,481, 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 9,774,481
-1 -9,774,481

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 9,774,481.

Example:
1 x 9,774,481 = 9,774,481
and
-1 x -9,774,481 = 9,774,481
Notice both answers equal 9,774,481

With that explanation out of the way, let's continue. Next, we take the number 9,774,481 and divide it by 2:

9,774,481 ÷ 2 = 4,887,240.5

If the quotient is a whole number, then 2 and 4,887,240.5 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 9,774,481
-1 -9,774,481

Now, we try dividing 9,774,481 by 3:

9,774,481 ÷ 3 = 3,258,160.3333

If the quotient is a whole number, then 3 and 3,258,160.3333 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 9,774,481
-1 -9,774,481

Let's try dividing by 4:

9,774,481 ÷ 4 = 2,443,620.25

If the quotient is a whole number, then 4 and 2,443,620.25 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 9,774,481
-1 9,774,481
Keep dividing by the next highest number until you cannot divide anymore.

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

17325752118,76138,033133,8979,774,481
-1-73-257-521-18,761-38,033-133,897-9,774,481
