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 111,453,215, 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 | 111,453,215 | |
| -1 | -111,453,215 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 111,453,215.
Example:
1 x 111,453,215 = 111,453,215
and
-1 x -111,453,215 = 111,453,215
Notice both answers equal 111,453,215
With that explanation out of the way, let's continue. Next, we take the number 111,453,215 and divide it by 2:
111,453,215 ÷ 2 = 55,726,607.5
If the quotient is a whole number, then 2 and 55,726,607.5 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 | 111,453,215 | |
| -1 | -111,453,215 |
Now, we try dividing 111,453,215 by 3:
111,453,215 ÷ 3 = 37,151,071.6667
If the quotient is a whole number, then 3 and 37,151,071.6667 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 | 111,453,215 | |
| -1 | -111,453,215 |
Let's try dividing by 4:
111,453,215 ÷ 4 = 27,863,303.75
If the quotient is a whole number, then 4 and 27,863,303.75 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 | 111,453,215 | |
| -1 | 111,453,215 |
If you did it right, you will end up with this table:
| 1 | 5 | 31 | 47 | 155 | 235 | 1,457 | 7,285 | 15,299 | 76,495 | 474,269 | 719,053 | 2,371,345 | 3,595,265 | 22,290,643 | 111,453,215 |
| -1 | -5 | -31 | -47 | -155 | -235 | -1,457 | -7,285 | -15,299 | -76,495 | -474,269 | -719,053 | -2,371,345 | -3,595,265 | -22,290,643 | -111,453,215 |
