How do I find the factor combinations of the number 272,203,747?

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 272,203,747, 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.

1 272,203,747
-1 -272,203,747

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 272,203,747.

Example:
1 x 272,203,747 = 272,203,747
and
-1 x -272,203,747 = 272,203,747
Notice both answers equal 272,203,747

With that explanation out of the way, let's continue. Next, we take the number 272,203,747 and divide it by 2:

272,203,747 ÷ 2 = 136,101,873.5

If the quotient is a whole number, then 2 and 136,101,873.5 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:

1 272,203,747
-1 -272,203,747

Now, we try dividing 272,203,747 by 3:

272,203,747 ÷ 3 = 90,734,582.3333

If the quotient is a whole number, then 3 and 90,734,582.3333 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:

1 272,203,747
-1 -272,203,747

Let's try dividing by 4:

272,203,747 ÷ 4 = 68,050,936.75

If the quotient is a whole number, then 4 and 68,050,936.75 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:

1 272,203,747
-1 272,203,747
Keep dividing by the next highest number until you cannot divide anymore.

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

119361754,02714,326,513272,203,747
-1-19-361-754,027-14,326,513-272,203,747
