How do I find the factor combinations of the number 202,220,219?

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 202,220,219, 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.

1 202,220,219
-1 -202,220,219

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 202,220,219.

Example:
1 x 202,220,219 = 202,220,219
and
-1 x -202,220,219 = 202,220,219
Notice both answers equal 202,220,219

With that explanation out of the way, let's continue. Next, we take the number 202,220,219 and divide it by 2:

202,220,219 ÷ 2 = 101,110,109.5

If the quotient is a whole number, then 2 and 101,110,109.5 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:

1 202,220,219
-1 -202,220,219

Now, we try dividing 202,220,219 by 3:

202,220,219 ÷ 3 = 67,406,739.6667

If the quotient is a whole number, then 3 and 67,406,739.6667 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:

1 202,220,219
-1 -202,220,219

Let's try dividing by 4:

202,220,219 ÷ 4 = 50,555,054.75

If the quotient is a whole number, then 4 and 50,555,054.75 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:

1 202,220,219
-1 202,220,219
Keep dividing by the next highest number until you cannot divide anymore.

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