How do I find the factor combinations of the number 76,301?

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 76,301, 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 76,301
-1 -76,301

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 76,301.

Example:
1 x 76,301 = 76,301
and
-1 x -76,301 = 76,301
Notice both answers equal 76,301

With that explanation out of the way, let's continue. Next, we take the number 76,301 and divide it by 2:

76,301 ÷ 2 = 38,150.5

If the quotient is a whole number, then 2 and 38,150.5 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 76,301
-1 -76,301

Now, we try dividing 76,301 by 3:

76,301 ÷ 3 = 25,433.6667

If the quotient is a whole number, then 3 and 25,433.6667 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 76,301
-1 -76,301

Let's try dividing by 4:

76,301 ÷ 4 = 19,075.25

If the quotient is a whole number, then 4 and 19,075.25 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 76,301
-1 76,301
Keep dividing by the next highest number until you cannot divide anymore.

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

1411,86176,301
-1-41-1,861-76,301
