How do I find the factor combinations of the number 1,135,313?

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 1,135,313, 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 1,135,313
-1 -1,135,313

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 1,135,313.

Example:
1 x 1,135,313 = 1,135,313
and
-1 x -1,135,313 = 1,135,313
Notice both answers equal 1,135,313

With that explanation out of the way, let's continue. Next, we take the number 1,135,313 and divide it by 2:

1,135,313 ÷ 2 = 567,656.5

If the quotient is a whole number, then 2 and 567,656.5 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 1,135,313
-1 -1,135,313

Now, we try dividing 1,135,313 by 3:

1,135,313 ÷ 3 = 378,437.6667

If the quotient is a whole number, then 3 and 378,437.6667 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 1,135,313
-1 -1,135,313

Let's try dividing by 4:

1,135,313 ÷ 4 = 283,828.25

If the quotient is a whole number, then 4 and 283,828.25 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 1,135,313
-1 1,135,313
Keep dividing by the next highest number until you cannot divide anymore.

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

131536911,64321,42136,6231,135,313
-1-31-53-691-1,643-21,421-36,623-1,135,313
