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 202,222,111, it is easier to work with a table - it's called factoring from the outside in.
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 | 202,222,111 | |
| -1 | -202,222,111 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 202,222,111.
Example:
1 x 202,222,111 = 202,222,111
and
-1 x -202,222,111 = 202,222,111
Notice both answers equal 202,222,111
With that explanation out of the way, let's continue. Next, we take the number 202,222,111 and divide it by 2:
202,222,111 ÷ 2 = 101,111,055.5
If the quotient is a whole number, then 2 and 101,111,055.5 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 | 202,222,111 | |
| -1 | -202,222,111 |
Now, we try dividing 202,222,111 by 3:
202,222,111 ÷ 3 = 67,407,370.3333
If the quotient is a whole number, then 3 and 67,407,370.3333 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 | 202,222,111 | |
| -1 | -202,222,111 |
Let's try dividing by 4:
202,222,111 ÷ 4 = 50,555,527.75
If the quotient is a whole number, then 4 and 50,555,527.75 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 | 202,222,111 | |
| -1 | 202,222,111 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 19 | 91 | 133 | 247 | 1,729 | 116,959 | 818,713 | 1,520,467 | 2,222,221 | 10,643,269 | 15,555,547 | 28,888,873 | 202,222,111 |
| -1 | -7 | -13 | -19 | -91 | -133 | -247 | -1,729 | -116,959 | -818,713 | -1,520,467 | -2,222,221 | -10,643,269 | -15,555,547 | -28,888,873 | -202,222,111 |
