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 222,401,105, 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 | 222,401,105 | |
| -1 | -222,401,105 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 222,401,105.
Example:
1 x 222,401,105 = 222,401,105
and
-1 x -222,401,105 = 222,401,105
Notice both answers equal 222,401,105
With that explanation out of the way, let's continue. Next, we take the number 222,401,105 and divide it by 2:
222,401,105 ÷ 2 = 111,200,552.5
If the quotient is a whole number, then 2 and 111,200,552.5 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 | 222,401,105 | |
| -1 | -222,401,105 |
Now, we try dividing 222,401,105 by 3:
222,401,105 ÷ 3 = 74,133,701.6667
If the quotient is a whole number, then 3 and 74,133,701.6667 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 | 222,401,105 | |
| -1 | -222,401,105 |
Let's try dividing by 4:
222,401,105 ÷ 4 = 55,600,276.25
If the quotient is a whole number, then 4 and 55,600,276.25 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 | 222,401,105 | |
| -1 | 222,401,105 |
If you did it right, you will end up with this table:
| 1 | 5 | 107 | 151 | 535 | 755 | 2,753 | 13,765 | 16,157 | 80,785 | 294,571 | 415,703 | 1,472,855 | 2,078,515 | 44,480,221 | 222,401,105 |
| -1 | -5 | -107 | -151 | -535 | -755 | -2,753 | -13,765 | -16,157 | -80,785 | -294,571 | -415,703 | -1,472,855 | -2,078,515 | -44,480,221 | -222,401,105 |
