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 222,512,303, 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 | 222,512,303 | |
| -1 | -222,512,303 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 222,512,303.
Example:
1 x 222,512,303 = 222,512,303
and
-1 x -222,512,303 = 222,512,303
Notice both answers equal 222,512,303
With that explanation out of the way, let's continue. Next, we take the number 222,512,303 and divide it by 2:
222,512,303 ÷ 2 = 111,256,151.5
If the quotient is a whole number, then 2 and 111,256,151.5 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 | 222,512,303 | |
| -1 | -222,512,303 |
Now, we try dividing 222,512,303 by 3:
222,512,303 ÷ 3 = 74,170,767.6667
If the quotient is a whole number, then 3 and 74,170,767.6667 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 | 222,512,303 | |
| -1 | -222,512,303 |
Let's try dividing by 4:
222,512,303 ÷ 4 = 55,628,075.75
If the quotient is a whole number, then 4 and 55,628,075.75 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 | 222,512,303 | |
| -1 | 222,512,303 |
If you did it right, you will end up with this table:
| 1 | 13 | 17 | 167 | 221 | 2,171 | 2,839 | 6,029 | 36,907 | 78,377 | 102,493 | 1,006,843 | 1,332,409 | 13,088,959 | 17,116,331 | 222,512,303 |
| -1 | -13 | -17 | -167 | -221 | -2,171 | -2,839 | -6,029 | -36,907 | -78,377 | -102,493 | -1,006,843 | -1,332,409 | -13,088,959 | -17,116,331 | -222,512,303 |
