How do I find the factor combinations of the number 9,293,891?

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 9,293,891, 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 9,293,891
-1 -9,293,891

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 9,293,891.

Example:
1 x 9,293,891 = 9,293,891
and
-1 x -9,293,891 = 9,293,891
Notice both answers equal 9,293,891

With that explanation out of the way, let's continue. Next, we take the number 9,293,891 and divide it by 2:

9,293,891 ÷ 2 = 4,646,945.5

If the quotient is a whole number, then 2 and 4,646,945.5 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 9,293,891
-1 -9,293,891

Now, we try dividing 9,293,891 by 3:

9,293,891 ÷ 3 = 3,097,963.6667

If the quotient is a whole number, then 3 and 3,097,963.6667 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 9,293,891
-1 -9,293,891

Let's try dividing by 4:

9,293,891 ÷ 4 = 2,323,472.75

If the quotient is a whole number, then 4 and 2,323,472.75 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 9,293,891
-1 9,293,891
Keep dividing by the next highest number until you cannot divide anymore.

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

129432578411,2477,45311,05136,163216,137320,4799,293,891
