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 111,303,415, 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 | 111,303,415 | |
| -1 | -111,303,415 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 111,303,415.
Example:
1 x 111,303,415 = 111,303,415
and
-1 x -111,303,415 = 111,303,415
Notice both answers equal 111,303,415
With that explanation out of the way, let's continue. Next, we take the number 111,303,415 and divide it by 2:
111,303,415 ÷ 2 = 55,651,707.5
If the quotient is a whole number, then 2 and 55,651,707.5 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 | 111,303,415 | |
| -1 | -111,303,415 |
Now, we try dividing 111,303,415 by 3:
111,303,415 ÷ 3 = 37,101,138.3333
If the quotient is a whole number, then 3 and 37,101,138.3333 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 | 111,303,415 | |
| -1 | -111,303,415 |
Let's try dividing by 4:
111,303,415 ÷ 4 = 27,825,853.75
If the quotient is a whole number, then 4 and 27,825,853.75 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 | 111,303,415 | |
| -1 | 111,303,415 |
If you did it right, you will end up with this table:
| 1 | 5 | 67 | 83 | 335 | 415 | 4,003 | 5,561 | 20,015 | 27,805 | 268,201 | 332,249 | 1,341,005 | 1,661,245 | 22,260,683 | 111,303,415 |
| -1 | -5 | -67 | -83 | -335 | -415 | -4,003 | -5,561 | -20,015 | -27,805 | -268,201 | -332,249 | -1,341,005 | -1,661,245 | -22,260,683 | -111,303,415 |
