How do I find the factor combinations of the number 340,925?

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 340,925, 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.

1 340,925
-1 -340,925

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 340,925.

Example:
1 x 340,925 = 340,925
and
-1 x -340,925 = 340,925
Notice both answers equal 340,925

With that explanation out of the way, let's continue. Next, we take the number 340,925 and divide it by 2:

340,925 ÷ 2 = 170,462.5

If the quotient is a whole number, then 2 and 170,462.5 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:

1 340,925
-1 -340,925

Now, we try dividing 340,925 by 3:

340,925 ÷ 3 = 113,641.6667

If the quotient is a whole number, then 3 and 113,641.6667 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:

1 340,925
-1 -340,925

Let's try dividing by 4:

340,925 ÷ 4 = 85,231.25

If the quotient is a whole number, then 4 and 85,231.25 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:

1 340,925
-1 340,925
Keep dividing by the next highest number until you cannot divide anymore.

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

151325653251,0495,24513,63726,22568,185340,925
-1-5-13-25-65-325-1,049-5,245-13,637-26,225-68,185-340,925
