How do I find the factor combinations of the number 201,541?

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 201,541, 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.

1 201,541
-1 -201,541

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 201,541.

Example:
1 x 201,541 = 201,541
and
-1 x -201,541 = 201,541
Notice both answers equal 201,541

With that explanation out of the way, let's continue. Next, we take the number 201,541 and divide it by 2:

201,541 ÷ 2 = 100,770.5

If the quotient is a whole number, then 2 and 100,770.5 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:

1 201,541
-1 -201,541

Now, we try dividing 201,541 by 3:

201,541 ÷ 3 = 67,180.3333

If the quotient is a whole number, then 3 and 67,180.3333 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:

1 201,541
-1 -201,541

Let's try dividing by 4:

201,541 ÷ 4 = 50,385.25

If the quotient is a whole number, then 4 and 50,385.25 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:

1 201,541
-1 201,541
Keep dividing by the next highest number until you cannot divide anymore.

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

1431091,8494,687201,541
-1-43-109-1,849-4,687-201,541
