How do I find the factor combinations of the number 782,383?

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 782,383, 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.

1 782,383
-1 -782,383

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 782,383.

Example:
1 x 782,383 = 782,383
and
-1 x -782,383 = 782,383
Notice both answers equal 782,383

With that explanation out of the way, let's continue. Next, we take the number 782,383 and divide it by 2:

782,383 ÷ 2 = 391,191.5

If the quotient is a whole number, then 2 and 391,191.5 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:

1 782,383
-1 -782,383

Now, we try dividing 782,383 by 3:

782,383 ÷ 3 = 260,794.3333

If the quotient is a whole number, then 3 and 260,794.3333 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:

1 782,383
-1 -782,383

Let's try dividing by 4:

782,383 ÷ 4 = 195,595.75

If the quotient is a whole number, then 4 and 195,595.75 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:

1 782,383
-1 782,383
Keep dividing by the next highest number until you cannot divide anymore.

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

17493432,28115,967111,769782,383
-1-7-49-343-2,281-15,967-111,769-782,383
