How do I find the factor combinations of the number 343,045?

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 343,045, 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.

1 343,045
-1 -343,045

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 343,045.

Example:
1 x 343,045 = 343,045
and
-1 x -343,045 = 343,045
Notice both answers equal 343,045

With that explanation out of the way, let's continue. Next, we take the number 343,045 and divide it by 2:

343,045 ÷ 2 = 171,522.5

If the quotient is a whole number, then 2 and 171,522.5 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:

1 343,045
-1 -343,045

Now, we try dividing 343,045 by 3:

343,045 ÷ 3 = 114,348.3333

If the quotient is a whole number, then 3 and 114,348.3333 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:

1 343,045
-1 -343,045

Let's try dividing by 4:

343,045 ÷ 4 = 85,761.25

If the quotient is a whole number, then 4 and 85,761.25 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:

1 343,045
-1 343,045
Keep dividing by the next highest number until you cannot divide anymore.

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

151923951151574377852,1852,9833,61114,91518,05568,609343,045
