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 111,313,445, 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 | 111,313,445 | |
| -1 | -111,313,445 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 111,313,445.
Example:
1 x 111,313,445 = 111,313,445
and
-1 x -111,313,445 = 111,313,445
Notice both answers equal 111,313,445
With that explanation out of the way, let's continue. Next, we take the number 111,313,445 and divide it by 2:
111,313,445 ÷ 2 = 55,656,722.5
If the quotient is a whole number, then 2 and 55,656,722.5 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 | 111,313,445 | |
| -1 | -111,313,445 |
Now, we try dividing 111,313,445 by 3:
111,313,445 ÷ 3 = 37,104,481.6667
If the quotient is a whole number, then 3 and 37,104,481.6667 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 | 111,313,445 | |
| -1 | -111,313,445 |
Let's try dividing by 4:
111,313,445 ÷ 4 = 27,828,361.25
If the quotient is a whole number, then 4 and 27,828,361.25 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 | 111,313,445 | |
| -1 | 111,313,445 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 71 | 115 | 355 | 1,633 | 8,165 | 13,633 | 68,165 | 313,559 | 967,943 | 1,567,795 | 4,839,715 | 22,262,689 | 111,313,445 |
| -1 | -5 | -23 | -71 | -115 | -355 | -1,633 | -8,165 | -13,633 | -68,165 | -313,559 | -967,943 | -1,567,795 | -4,839,715 | -22,262,689 | -111,313,445 |
