How do I find the factor combinations of the number 25,529,172?

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 25,529,172, 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 25,529,172
-1 -25,529,172

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 25,529,172.

Example:
1 x 25,529,172 = 25,529,172
and
-1 x -25,529,172 = 25,529,172
Notice both answers equal 25,529,172

With that explanation out of the way, let's continue. Next, we take the number 25,529,172 and divide it by 2:

25,529,172 ÷ 2 = 12,764,586

If the quotient is a whole number, then 2 and 12,764,586 are factors. In this case, the quotient is a whole number. Write them in the table inside the other two factors like the below example. Don't forget to write the negative numbers too!

Here is what our table should look like at this step:

1 2 12,764,586 25,529,172
-1 -2 -12,764,586 -25,529,172

Now, we try dividing 25,529,172 by 3:

25,529,172 ÷ 3 = 8,509,724

If the quotient is a whole number, then 3 and 8,509,724 are factors. In this case, the quotient is a whole number. Write them in the table inside the other two factors like the below example. Don't forget to write the negative numbers too!

Here is what our table should look like at this step:

1 2 3 8,509,724 12,764,586 25,529,172
-1 -2 -3 -8,509,724 -12,764,586 -25,529,172

Let's try dividing by 4:

25,529,172 ÷ 4 = 6,382,293

If the quotient is a whole number, then 4 and 6,382,293 are factors. In this case, the quotient is a whole number. Write them in the table inside the other two factors like the below example. Don't forget to write the negative numbers too!

Here is what our table should look like at this step:

1 2 3 4 6,382,293 8,509,724 12,764,586 25,529,172
-1 -2 -3 -4 -6,382,293 -8,509,724 -12,764,586 25,529,172
Keep dividing by the next highest number until you cannot divide anymore.

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