How do I find the factor combinations of the number 79,195,529?

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 79,195,529, 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 79,195,529
-1 -79,195,529

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 79,195,529.

Example:
1 x 79,195,529 = 79,195,529
and
-1 x -79,195,529 = 79,195,529
Notice both answers equal 79,195,529

With that explanation out of the way, let's continue. Next, we take the number 79,195,529 and divide it by 2:

79,195,529 ÷ 2 = 39,597,764.5

If the quotient is a whole number, then 2 and 39,597,764.5 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 79,195,529
-1 -79,195,529

Now, we try dividing 79,195,529 by 3:

79,195,529 ÷ 3 = 26,398,509.6667

If the quotient is a whole number, then 3 and 26,398,509.6667 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 79,195,529
-1 -79,195,529

Let's try dividing by 4:

79,195,529 ÷ 4 = 19,798,882.25

If the quotient is a whole number, then 4 and 19,798,882.25 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 79,195,529
-1 79,195,529
Keep dividing by the next highest number until you cannot divide anymore.

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

1783581136,309954,16311,313,64779,195,529
