How do I find the factor combinations of the number 29,057,755?

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 29,057,755, 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 29,057,755
-1 -29,057,755

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 29,057,755.

Example:
1 x 29,057,755 = 29,057,755
and
-1 x -29,057,755 = 29,057,755
Notice both answers equal 29,057,755

With that explanation out of the way, let's continue. Next, we take the number 29,057,755 and divide it by 2:

29,057,755 ÷ 2 = 14,528,877.5

If the quotient is a whole number, then 2 and 14,528,877.5 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 29,057,755
-1 -29,057,755

Now, we try dividing 29,057,755 by 3:

29,057,755 ÷ 3 = 9,685,918.3333

If the quotient is a whole number, then 3 and 9,685,918.3333 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 29,057,755
-1 -29,057,755

Let's try dividing by 4:

29,057,755 ÷ 4 = 7,264,438.75

If the quotient is a whole number, then 4 and 7,264,438.75 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 29,057,755
-1 29,057,755
Keep dividing by the next highest number until you cannot divide anymore.

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

151,2314,7216,15523,6055,811,55129,057,755
