How do I find the factor combinations of the number 33,070,261?

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 33,070,261, 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 33,070,261
-1 -33,070,261

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 33,070,261.

Example:
1 x 33,070,261 = 33,070,261
and
-1 x -33,070,261 = 33,070,261
Notice both answers equal 33,070,261

With that explanation out of the way, let's continue. Next, we take the number 33,070,261 and divide it by 2:

33,070,261 ÷ 2 = 16,535,130.5

If the quotient is a whole number, then 2 and 16,535,130.5 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 33,070,261
-1 -33,070,261

Now, we try dividing 33,070,261 by 3:

33,070,261 ÷ 3 = 11,023,420.3333

If the quotient is a whole number, then 3 and 11,023,420.3333 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 33,070,261
-1 -33,070,261

Let's try dividing by 4:

33,070,261 ÷ 4 = 8,267,565.25

If the quotient is a whole number, then 4 and 8,267,565.25 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 33,070,261
-1 33,070,261
Keep dividing by the next highest number until you cannot divide anymore.

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

172411,68719,603137,2214,724,32333,070,261
-1-7-241-1,687-19,603-137,221-4,724,323-33,070,261
