How do I find the factor combinations of the number 262,591?

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 262,591, 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.

1 262,591
-1 -262,591

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 262,591.

Example:
1 x 262,591 = 262,591
and
-1 x -262,591 = 262,591
Notice both answers equal 262,591

With that explanation out of the way, let's continue. Next, we take the number 262,591 and divide it by 2:

262,591 ÷ 2 = 131,295.5

If the quotient is a whole number, then 2 and 131,295.5 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:

1 262,591
-1 -262,591

Now, we try dividing 262,591 by 3:

262,591 ÷ 3 = 87,530.3333

If the quotient is a whole number, then 3 and 87,530.3333 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:

1 262,591
-1 -262,591

Let's try dividing by 4:

262,591 ÷ 4 = 65,647.75

If the quotient is a whole number, then 4 and 65,647.75 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:

1 262,591
-1 262,591
Keep dividing by the next highest number until you cannot divide anymore.

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

1723491612331,1271,6315,35911,41737,513262,591
-1-7-23-49-161-233-1,127-1,631-5,359-11,417-37,513-262,591
