How do I find the factor combinations of the number 486,761?

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 486,761, 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.

1 486,761
-1 -486,761

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 486,761.

Example:
1 x 486,761 = 486,761
and
-1 x -486,761 = 486,761
Notice both answers equal 486,761

With that explanation out of the way, let's continue. Next, we take the number 486,761 and divide it by 2:

486,761 ÷ 2 = 243,380.5

If the quotient is a whole number, then 2 and 243,380.5 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:

1 486,761
-1 -486,761

Now, we try dividing 486,761 by 3:

486,761 ÷ 3 = 162,253.6667

If the quotient is a whole number, then 3 and 162,253.6667 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:

1 486,761
-1 -486,761

Let's try dividing by 4:

486,761 ÷ 4 = 121,690.25

If the quotient is a whole number, then 4 and 121,690.25 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:

1 486,761
-1 486,761
Keep dividing by the next highest number until you cannot divide anymore.

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

11117191371872093231,5072,3292,6033,55325,61928,63344,251486,761
