How do I find the factor combinations of the number 276,635?

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 276,635, 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.

1 276,635
-1 -276,635

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 276,635.

Example:
1 x 276,635 = 276,635
and
-1 x -276,635 = 276,635
Notice both answers equal 276,635

With that explanation out of the way, let's continue. Next, we take the number 276,635 and divide it by 2:

276,635 ÷ 2 = 138,317.5

If the quotient is a whole number, then 2 and 138,317.5 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:

1 276,635
-1 -276,635

Now, we try dividing 276,635 by 3:

276,635 ÷ 3 = 92,211.6667

If the quotient is a whole number, then 3 and 92,211.6667 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:

1 276,635
-1 -276,635

Let's try dividing by 4:

276,635 ÷ 4 = 69,158.75

If the quotient is a whole number, then 4 and 69,158.75 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:

1 276,635
-1 276,635
Keep dividing by the next highest number until you cannot divide anymore.

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

15613059074,53555,327276,635
-1-5-61-305-907-4,535-55,327-276,635
