How do I find the factor combinations of the number 47,674,753?

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 47,674,753, 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 47,674,753
-1 -47,674,753

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 47,674,753.

Example:
1 x 47,674,753 = 47,674,753
and
-1 x -47,674,753 = 47,674,753
Notice both answers equal 47,674,753

With that explanation out of the way, let's continue. Next, we take the number 47,674,753 and divide it by 2:

47,674,753 ÷ 2 = 23,837,376.5

If the quotient is a whole number, then 2 and 23,837,376.5 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 47,674,753
-1 -47,674,753

Now, we try dividing 47,674,753 by 3:

47,674,753 ÷ 3 = 15,891,584.3333

If the quotient is a whole number, then 3 and 15,891,584.3333 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 47,674,753
-1 -47,674,753

Let's try dividing by 4:

47,674,753 ÷ 4 = 11,918,688.25

If the quotient is a whole number, then 4 and 11,918,688.25 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 47,674,753
-1 47,674,753
Keep dividing by the next highest number until you cannot divide anymore.

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

1729203234,8511,643,9576,810,67947,674,753
-1-7-29-203-234,851-1,643,957-6,810,679-47,674,753
