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 222,201,101, 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 | 222,201,101 | |
| -1 | -222,201,101 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 222,201,101.
Example:
1 x 222,201,101 = 222,201,101
and
-1 x -222,201,101 = 222,201,101
Notice both answers equal 222,201,101
With that explanation out of the way, let's continue. Next, we take the number 222,201,101 and divide it by 2:
222,201,101 ÷ 2 = 111,100,550.5
If the quotient is a whole number, then 2 and 111,100,550.5 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 | 222,201,101 | |
| -1 | -222,201,101 |
Now, we try dividing 222,201,101 by 3:
222,201,101 ÷ 3 = 74,067,033.6667
If the quotient is a whole number, then 3 and 74,067,033.6667 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 | 222,201,101 | |
| -1 | -222,201,101 |
Let's try dividing by 4:
222,201,101 ÷ 4 = 55,550,275.25
If the quotient is a whole number, then 4 and 55,550,275.25 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 | 222,201,101 | |
| -1 | 222,201,101 |
If you did it right, you will end up with this table:
| 1 | 17 | 47 | 61 | 97 | 799 | 1,037 | 1,649 | 2,209 | 2,867 | 4,559 | 5,917 | 37,553 | 48,739 | 77,503 | 100,589 | 134,749 | 214,273 | 278,099 | 2,290,733 | 3,642,641 | 4,727,683 | 13,070,653 | 222,201,101 |
| -1 | -17 | -47 | -61 | -97 | -799 | -1,037 | -1,649 | -2,209 | -2,867 | -4,559 | -5,917 | -37,553 | -48,739 | -77,503 | -100,589 | -134,749 | -214,273 | -278,099 | -2,290,733 | -3,642,641 | -4,727,683 | -13,070,653 | -222,201,101 |
