How do I find the factor combinations of the number 339,365?

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 339,365, 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.

1 339,365
-1 -339,365

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 339,365.

Example:
1 x 339,365 = 339,365
and
-1 x -339,365 = 339,365
Notice both answers equal 339,365

With that explanation out of the way, let's continue. Next, we take the number 339,365 and divide it by 2:

339,365 ÷ 2 = 169,682.5

If the quotient is a whole number, then 2 and 169,682.5 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:

1 339,365
-1 -339,365

Now, we try dividing 339,365 by 3:

339,365 ÷ 3 = 113,121.6667

If the quotient is a whole number, then 3 and 113,121.6667 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:

1 339,365
-1 -339,365

Let's try dividing by 4:

339,365 ÷ 4 = 84,841.25

If the quotient is a whole number, then 4 and 84,841.25 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:

1 339,365
-1 339,365
Keep dividing by the next highest number until you cannot divide anymore.

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

151323651152272991,1351,4952,9515,22114,75526,10567,873339,365
