How do I find the factor combinations of the number 384,865?

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 384,865, 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.

1 384,865
-1 -384,865

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 384,865.

Example:
1 x 384,865 = 384,865
and
-1 x -384,865 = 384,865
Notice both answers equal 384,865

With that explanation out of the way, let's continue. Next, we take the number 384,865 and divide it by 2:

384,865 ÷ 2 = 192,432.5

If the quotient is a whole number, then 2 and 192,432.5 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:

1 384,865
-1 -384,865

Now, we try dividing 384,865 by 3:

384,865 ÷ 3 = 128,288.3333

If the quotient is a whole number, then 3 and 128,288.3333 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:

1 384,865
-1 -384,865

Let's try dividing by 4:

384,865 ÷ 4 = 96,216.25

If the quotient is a whole number, then 4 and 96,216.25 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:

1 384,865
-1 384,865
Keep dividing by the next highest number until you cannot divide anymore.

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

151331651551914039552,0152,4835,92112,41529,60576,973384,865
