How do I find the factor combinations of the number 29,925,553?

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 29,925,553, 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 29,925,553
-1 -29,925,553

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 29,925,553.

Example:
1 x 29,925,553 = 29,925,553
and
-1 x -29,925,553 = 29,925,553
Notice both answers equal 29,925,553

With that explanation out of the way, let's continue. Next, we take the number 29,925,553 and divide it by 2:

29,925,553 ÷ 2 = 14,962,776.5

If the quotient is a whole number, then 2 and 14,962,776.5 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 29,925,553
-1 -29,925,553

Now, we try dividing 29,925,553 by 3:

29,925,553 ÷ 3 = 9,975,184.3333

If the quotient is a whole number, then 3 and 9,975,184.3333 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 29,925,553
-1 -29,925,553

Let's try dividing by 4:

29,925,553 ÷ 4 = 7,481,388.25

If the quotient is a whole number, then 4 and 7,481,388.25 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 29,925,553
-1 29,925,553
Keep dividing by the next highest number until you cannot divide anymore.

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

1723161185,8731,301,1114,275,07929,925,553
-1-7-23-161-185,873-1,301,111-4,275,079-29,925,553
