How do I find the factor combinations of the number 972,025?

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 972,025, 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.

1 972,025
-1 -972,025

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 972,025.

Example:
1 x 972,025 = 972,025
and
-1 x -972,025 = 972,025
Notice both answers equal 972,025

With that explanation out of the way, let's continue. Next, we take the number 972,025 and divide it by 2:

972,025 ÷ 2 = 486,012.5

If the quotient is a whole number, then 2 and 486,012.5 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:

1 972,025
-1 -972,025

Now, we try dividing 972,025 by 3:

972,025 ÷ 3 = 324,008.3333

If the quotient is a whole number, then 3 and 324,008.3333 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:

1 972,025
-1 -972,025

Let's try dividing by 4:

972,025 ÷ 4 = 243,006.25

If the quotient is a whole number, then 4 and 243,006.25 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:

1 972,025
-1 972,025
Keep dividing by the next highest number until you cannot divide anymore.

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

1525592956591,4753,29516,47538,881194,405972,025
-1-5-25-59-295-659-1,475-3,295-16,475-38,881-194,405-972,025
