How do I find the factor combinations of the number 374,213,243?

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 374,213,243, 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.

1 374,213,243
-1 -374,213,243

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 374,213,243.

Example:
1 x 374,213,243 = 374,213,243
and
-1 x -374,213,243 = 374,213,243
Notice both answers equal 374,213,243

With that explanation out of the way, let's continue. Next, we take the number 374,213,243 and divide it by 2:

374,213,243 ÷ 2 = 187,106,621.5

If the quotient is a whole number, then 2 and 187,106,621.5 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:

1 374,213,243
-1 -374,213,243

Now, we try dividing 374,213,243 by 3:

374,213,243 ÷ 3 = 124,737,747.6667

If the quotient is a whole number, then 3 and 124,737,747.6667 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:

1 374,213,243
-1 -374,213,243

Let's try dividing by 4:

374,213,243 ÷ 4 = 93,553,310.75

If the quotient is a whole number, then 4 and 93,553,310.75 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:

1 374,213,243
-1 374,213,243
Keep dividing by the next highest number until you cannot divide anymore.

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

12359313,63927,437631,05116,270,141374,213,243
