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 222,204,025, 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 | 222,204,025 | |
| -1 | -222,204,025 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 222,204,025.
Example:
1 x 222,204,025 = 222,204,025
and
-1 x -222,204,025 = 222,204,025
Notice both answers equal 222,204,025
With that explanation out of the way, let's continue. Next, we take the number 222,204,025 and divide it by 2:
222,204,025 ÷ 2 = 111,102,012.5
If the quotient is a whole number, then 2 and 111,102,012.5 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 | 222,204,025 | |
| -1 | -222,204,025 |
Now, we try dividing 222,204,025 by 3:
222,204,025 ÷ 3 = 74,068,008.3333
If the quotient is a whole number, then 3 and 74,068,008.3333 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 | 222,204,025 | |
| -1 | -222,204,025 |
Let's try dividing by 4:
222,204,025 ÷ 4 = 55,551,006.25
If the quotient is a whole number, then 4 and 55,551,006.25 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 | 222,204,025 | |
| -1 | 222,204,025 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 25 | 85 | 251 | 425 | 1,255 | 2,083 | 4,267 | 6,275 | 10,415 | 21,335 | 35,411 | 52,075 | 106,675 | 177,055 | 522,833 | 885,275 | 2,614,165 | 8,888,161 | 13,070,825 | 44,440,805 | 222,204,025 |
| -1 | -5 | -17 | -25 | -85 | -251 | -425 | -1,255 | -2,083 | -4,267 | -6,275 | -10,415 | -21,335 | -35,411 | -52,075 | -106,675 | -177,055 | -522,833 | -885,275 | -2,614,165 | -8,888,161 | -13,070,825 | -44,440,805 | -222,204,025 |
