How do I find the factor combinations of the number 40,304,225?

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 40,304,225, 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 40,304,225
-1 -40,304,225

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 40,304,225.

Example:
1 x 40,304,225 = 40,304,225
and
-1 x -40,304,225 = 40,304,225
Notice both answers equal 40,304,225

With that explanation out of the way, let's continue. Next, we take the number 40,304,225 and divide it by 2:

40,304,225 ÷ 2 = 20,152,112.5

If the quotient is a whole number, then 2 and 20,152,112.5 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 40,304,225
-1 -40,304,225

Now, we try dividing 40,304,225 by 3:

40,304,225 ÷ 3 = 13,434,741.6667

If the quotient is a whole number, then 3 and 13,434,741.6667 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 40,304,225
-1 -40,304,225

Let's try dividing by 4:

40,304,225 ÷ 4 = 10,076,056.25

If the quotient is a whole number, then 4 and 10,076,056.25 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 40,304,225
-1 40,304,225
Keep dividing by the next highest number until you cannot divide anymore.

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