How do I find the factor combinations of the number 262,405?

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 262,405, 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.

1 262,405
-1 -262,405

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 262,405.

Example:
1 x 262,405 = 262,405
and
-1 x -262,405 = 262,405
Notice both answers equal 262,405

With that explanation out of the way, let's continue. Next, we take the number 262,405 and divide it by 2:

262,405 ÷ 2 = 131,202.5

If the quotient is a whole number, then 2 and 131,202.5 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:

1 262,405
-1 -262,405

Now, we try dividing 262,405 by 3:

262,405 ÷ 3 = 87,468.3333

If the quotient is a whole number, then 3 and 87,468.3333 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:

1 262,405
-1 -262,405

Let's try dividing by 4:

262,405 ÷ 4 = 65,601.25

If the quotient is a whole number, then 4 and 65,601.25 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:

1 262,405
-1 262,405
Keep dividing by the next highest number until you cannot divide anymore.

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

15111355651433677151,8354,0374,77120,18523,85552,481262,405
