How do I find the factor combinations of the number 3,676,135?

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 3,676,135, 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 3,676,135
-1 -3,676,135

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 3,676,135.

Example:
1 x 3,676,135 = 3,676,135
and
-1 x -3,676,135 = 3,676,135
Notice both answers equal 3,676,135

With that explanation out of the way, let's continue. Next, we take the number 3,676,135 and divide it by 2:

3,676,135 ÷ 2 = 1,838,067.5

If the quotient is a whole number, then 2 and 1,838,067.5 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 3,676,135
-1 -3,676,135

Now, we try dividing 3,676,135 by 3:

3,676,135 ÷ 3 = 1,225,378.3333

If the quotient is a whole number, then 3 and 1,225,378.3333 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 3,676,135
-1 -3,676,135

Let's try dividing by 4:

3,676,135 ÷ 4 = 919,033.75

If the quotient is a whole number, then 4 and 919,033.75 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 3,676,135
-1 3,676,135
Keep dividing by the next highest number until you cannot divide anymore.

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

1531371551856411,1473,2055,73519,87123,71799,355118,585735,2273,676,135
