How do I find the factor combinations of the number 986,953?

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 986,953, 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.

1 986,953
-1 -986,953

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 986,953.

Example:
1 x 986,953 = 986,953
and
-1 x -986,953 = 986,953
Notice both answers equal 986,953

With that explanation out of the way, let's continue. Next, we take the number 986,953 and divide it by 2:

986,953 ÷ 2 = 493,476.5

If the quotient is a whole number, then 2 and 493,476.5 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:

1 986,953
-1 -986,953

Now, we try dividing 986,953 by 3:

986,953 ÷ 3 = 328,984.3333

If the quotient is a whole number, then 3 and 328,984.3333 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:

1 986,953
-1 -986,953

Let's try dividing by 4:

986,953 ÷ 4 = 246,738.25

If the quotient is a whole number, then 4 and 246,738.25 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:

1 986,953
-1 986,953
Keep dividing by the next highest number until you cannot divide anymore.

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

1112347832535179131,0811,9093,90111,89120,99942,91189,723986,953
