How do I find the factor combinations of the number 271,915?

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 271,915, 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.

1 271,915
-1 -271,915

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 271,915.

Example:
1 x 271,915 = 271,915
and
-1 x -271,915 = 271,915
Notice both answers equal 271,915

With that explanation out of the way, let's continue. Next, we take the number 271,915 and divide it by 2:

271,915 ÷ 2 = 135,957.5

If the quotient is a whole number, then 2 and 135,957.5 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:

1 271,915
-1 -271,915

Now, we try dividing 271,915 by 3:

271,915 ÷ 3 = 90,638.3333

If the quotient is a whole number, then 3 and 90,638.3333 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:

1 271,915
-1 -271,915

Let's try dividing by 4:

271,915 ÷ 4 = 67,978.75

If the quotient is a whole number, then 4 and 67,978.75 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:

1 271,915
-1 271,915
Keep dividing by the next highest number until you cannot divide anymore.

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

1571735851194575952,2853,1997,76915,99538,84554,383271,915
-1-5-7-17-35-85-119-457-595-2,285-3,199-7,769-15,995-38,845-54,383-271,915
