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 222,524,015, 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 | 222,524,015 | |
| -1 | -222,524,015 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 222,524,015.
Example:
1 x 222,524,015 = 222,524,015
and
-1 x -222,524,015 = 222,524,015
Notice both answers equal 222,524,015
With that explanation out of the way, let's continue. Next, we take the number 222,524,015 and divide it by 2:
222,524,015 ÷ 2 = 111,262,007.5
If the quotient is a whole number, then 2 and 111,262,007.5 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 | 222,524,015 | |
| -1 | -222,524,015 |
Now, we try dividing 222,524,015 by 3:
222,524,015 ÷ 3 = 74,174,671.6667
If the quotient is a whole number, then 3 and 74,174,671.6667 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 | 222,524,015 | |
| -1 | -222,524,015 |
Let's try dividing by 4:
222,524,015 ÷ 4 = 55,631,003.75
If the quotient is a whole number, then 4 and 55,631,003.75 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 | 222,524,015 | |
| -1 | 222,524,015 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 41 | 205 | 287 | 1,435 | 155,069 | 775,345 | 1,085,483 | 5,427,415 | 6,357,829 | 31,789,145 | 44,504,803 | 222,524,015 |
| -1 | -5 | -7 | -35 | -41 | -205 | -287 | -1,435 | -155,069 | -775,345 | -1,085,483 | -5,427,415 | -6,357,829 | -31,789,145 | -44,504,803 | -222,524,015 |
