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 222,015,025, 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 | 222,015,025 | |
| -1 | -222,015,025 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 222,015,025.
Example:
1 x 222,015,025 = 222,015,025
and
-1 x -222,015,025 = 222,015,025
Notice both answers equal 222,015,025
With that explanation out of the way, let's continue. Next, we take the number 222,015,025 and divide it by 2:
222,015,025 ÷ 2 = 111,007,512.5
If the quotient is a whole number, then 2 and 111,007,512.5 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 | 222,015,025 | |
| -1 | -222,015,025 |
Now, we try dividing 222,015,025 by 3:
222,015,025 ÷ 3 = 74,005,008.3333
If the quotient is a whole number, then 3 and 74,005,008.3333 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 | 222,015,025 | |
| -1 | -222,015,025 |
Let's try dividing by 4:
222,015,025 ÷ 4 = 55,503,756.25
If the quotient is a whole number, then 4 and 55,503,756.25 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 | 222,015,025 | |
| -1 | 222,015,025 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 31 | 155 | 775 | 961 | 4,805 | 9,241 | 24,025 | 46,205 | 231,025 | 286,471 | 1,432,355 | 7,161,775 | 8,880,601 | 44,403,005 | 222,015,025 |
| -1 | -5 | -25 | -31 | -155 | -775 | -961 | -4,805 | -9,241 | -24,025 | -46,205 | -231,025 | -286,471 | -1,432,355 | -7,161,775 | -8,880,601 | -44,403,005 | -222,015,025 |
