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 222,503,755, 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 | 222,503,755 | |
| -1 | -222,503,755 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 222,503,755.
Example:
1 x 222,503,755 = 222,503,755
and
-1 x -222,503,755 = 222,503,755
Notice both answers equal 222,503,755
With that explanation out of the way, let's continue. Next, we take the number 222,503,755 and divide it by 2:
222,503,755 ÷ 2 = 111,251,877.5
If the quotient is a whole number, then 2 and 111,251,877.5 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 | 222,503,755 | |
| -1 | -222,503,755 |
Now, we try dividing 222,503,755 by 3:
222,503,755 ÷ 3 = 74,167,918.3333
If the quotient is a whole number, then 3 and 74,167,918.3333 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 | 222,503,755 | |
| -1 | -222,503,755 |
Let's try dividing by 4:
222,503,755 ÷ 4 = 55,625,938.75
If the quotient is a whole number, then 4 and 55,625,938.75 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 | 222,503,755 | |
| -1 | 222,503,755 |
If you did it right, you will end up with this table:
| 1 | 5 | 37 | 137 | 185 | 685 | 5,069 | 8,779 | 25,345 | 43,895 | 324,823 | 1,202,723 | 1,624,115 | 6,013,615 | 44,500,751 | 222,503,755 |
| -1 | -5 | -37 | -137 | -185 | -685 | -5,069 | -8,779 | -25,345 | -43,895 | -324,823 | -1,202,723 | -1,624,115 | -6,013,615 | -44,500,751 | -222,503,755 |
