How do I find the factor combinations of the number 32,178,307?

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 32,178,307, 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 32,178,307
-1 -32,178,307

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 32,178,307.

Example:
1 x 32,178,307 = 32,178,307
and
-1 x -32,178,307 = 32,178,307
Notice both answers equal 32,178,307

With that explanation out of the way, let's continue. Next, we take the number 32,178,307 and divide it by 2:

32,178,307 ÷ 2 = 16,089,153.5

If the quotient is a whole number, then 2 and 16,089,153.5 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 32,178,307
-1 -32,178,307

Now, we try dividing 32,178,307 by 3:

32,178,307 ÷ 3 = 10,726,102.3333

If the quotient is a whole number, then 3 and 10,726,102.3333 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 32,178,307
-1 -32,178,307

Let's try dividing by 4:

32,178,307 ÷ 4 = 8,044,576.75

If the quotient is a whole number, then 4 and 8,044,576.75 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 32,178,307
-1 32,178,307
Keep dividing by the next highest number until you cannot divide anymore.

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

174,596,90132,178,307
-1-7-4,596,901-32,178,307
