How do I find the factor combinations of the number 12,941,201?

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 12,941,201, 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 12,941,201
-1 -12,941,201

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 12,941,201.

Example:
1 x 12,941,201 = 12,941,201
and
-1 x -12,941,201 = 12,941,201
Notice both answers equal 12,941,201

With that explanation out of the way, let's continue. Next, we take the number 12,941,201 and divide it by 2:

12,941,201 ÷ 2 = 6,470,600.5

If the quotient is a whole number, then 2 and 6,470,600.5 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 12,941,201
-1 -12,941,201

Now, we try dividing 12,941,201 by 3:

12,941,201 ÷ 3 = 4,313,733.6667

If the quotient is a whole number, then 3 and 4,313,733.6667 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 12,941,201
-1 -12,941,201

Let's try dividing by 4:

12,941,201 ÷ 4 = 3,235,300.25

If the quotient is a whole number, then 4 and 3,235,300.25 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 12,941,201
-1 12,941,201
Keep dividing by the next highest number until you cannot divide anymore.

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

171391142,211995,4771,848,74312,941,201
-1-7-13-91-142,211-995,477-1,848,743-12,941,201
