How do I find the factor combinations of the number 101,550,172?

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 101,550,172, 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.

1 101,550,172
-1 -101,550,172

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 101,550,172.

Example:
1 x 101,550,172 = 101,550,172
and
-1 x -101,550,172 = 101,550,172
Notice both answers equal 101,550,172

With that explanation out of the way, let's continue. Next, we take the number 101,550,172 and divide it by 2:

101,550,172 ÷ 2 = 50,775,086

If the quotient is a whole number, then 2 and 50,775,086 are factors. In this case, the quotient is a whole number. Write them in the table inside the other two factors like the below example. Don't forget to write the negative numbers too!

Here is what our table should look like at this step:

1 2 50,775,086 101,550,172
-1 -2 -50,775,086 -101,550,172

Now, we try dividing 101,550,172 by 3:

101,550,172 ÷ 3 = 33,850,057.3333

If the quotient is a whole number, then 3 and 33,850,057.3333 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 2 50,775,086 101,550,172
-1 -2 -50,775,086 -101,550,172

Let's try dividing by 4:

101,550,172 ÷ 4 = 25,387,543

If the quotient is a whole number, then 4 and 25,387,543 are factors. In this case, the quotient is a whole number. Write them in the table inside the other two factors like the below example. Don't forget to write the negative numbers too!

Here is what our table should look like at this step:

1 2 4 25,387,543 50,775,086 101,550,172
-1 -2 -4 -25,387,543 -50,775,086 101,550,172
Keep dividing by the next highest number until you cannot divide anymore.

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

12431621031242064123,1936,3867,95112,77215,90231,804246,481492,962818,953985,9241,637,9063,275,81225,387,54350,775,086101,550,172
