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 222,240,265, 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 | 222,240,265 | |
| -1 | -222,240,265 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 222,240,265.
Example:
1 x 222,240,265 = 222,240,265
and
-1 x -222,240,265 = 222,240,265
Notice both answers equal 222,240,265
With that explanation out of the way, let's continue. Next, we take the number 222,240,265 and divide it by 2:
222,240,265 ÷ 2 = 111,120,132.5
If the quotient is a whole number, then 2 and 111,120,132.5 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 | 222,240,265 | |
| -1 | -222,240,265 |
Now, we try dividing 222,240,265 by 3:
222,240,265 ÷ 3 = 74,080,088.3333
If the quotient is a whole number, then 3 and 74,080,088.3333 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 | 222,240,265 | |
| -1 | -222,240,265 |
Let's try dividing by 4:
222,240,265 ÷ 4 = 55,560,066.25
If the quotient is a whole number, then 4 and 55,560,066.25 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 | 222,240,265 | |
| -1 | 222,240,265 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 65 | 727 | 3,635 | 4,703 | 9,451 | 23,515 | 47,255 | 61,139 | 305,695 | 3,419,081 | 17,095,405 | 44,448,053 | 222,240,265 |
| -1 | -5 | -13 | -65 | -727 | -3,635 | -4,703 | -9,451 | -23,515 | -47,255 | -61,139 | -305,695 | -3,419,081 | -17,095,405 | -44,448,053 | -222,240,265 |
