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 111,315,425, 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 | 111,315,425 | |
| -1 | -111,315,425 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 111,315,425.
Example:
1 x 111,315,425 = 111,315,425
and
-1 x -111,315,425 = 111,315,425
Notice both answers equal 111,315,425
With that explanation out of the way, let's continue. Next, we take the number 111,315,425 and divide it by 2:
111,315,425 ÷ 2 = 55,657,712.5
If the quotient is a whole number, then 2 and 55,657,712.5 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 | 111,315,425 | |
| -1 | -111,315,425 |
Now, we try dividing 111,315,425 by 3:
111,315,425 ÷ 3 = 37,105,141.6667
If the quotient is a whole number, then 3 and 37,105,141.6667 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 | 111,315,425 | |
| -1 | -111,315,425 |
Let's try dividing by 4:
111,315,425 ÷ 4 = 27,828,856.25
If the quotient is a whole number, then 4 and 27,828,856.25 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 | 111,315,425 | |
| -1 | 111,315,425 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 25 | 37 | 65 | 185 | 325 | 481 | 925 | 2,405 | 9,257 | 12,025 | 46,285 | 120,341 | 231,425 | 342,509 | 601,705 | 1,712,545 | 3,008,525 | 4,452,617 | 8,562,725 | 22,263,085 | 111,315,425 |
| -1 | -5 | -13 | -25 | -37 | -65 | -185 | -325 | -481 | -925 | -2,405 | -9,257 | -12,025 | -46,285 | -120,341 | -231,425 | -342,509 | -601,705 | -1,712,545 | -3,008,525 | -4,452,617 | -8,562,725 | -22,263,085 | -111,315,425 |
