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 111,243,407, 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 | 111,243,407 | |
| -1 | -111,243,407 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 111,243,407.
Example:
1 x 111,243,407 = 111,243,407
and
-1 x -111,243,407 = 111,243,407
Notice both answers equal 111,243,407
With that explanation out of the way, let's continue. Next, we take the number 111,243,407 and divide it by 2:
111,243,407 ÷ 2 = 55,621,703.5
If the quotient is a whole number, then 2 and 55,621,703.5 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 | 111,243,407 | |
| -1 | -111,243,407 |
Now, we try dividing 111,243,407 by 3:
111,243,407 ÷ 3 = 37,081,135.6667
If the quotient is a whole number, then 3 and 37,081,135.6667 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 | 111,243,407 | |
| -1 | -111,243,407 |
Let's try dividing by 4:
111,243,407 ÷ 4 = 27,810,851.75
If the quotient is a whole number, then 4 and 27,810,851.75 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 | 111,243,407 | |
| -1 | 111,243,407 |
If you did it right, you will end up with this table:
| 1 | 11 | 31 | 47 | 121 | 341 | 517 | 631 | 1,457 | 3,751 | 5,687 | 6,941 | 16,027 | 19,561 | 29,657 | 76,351 | 176,297 | 215,171 | 326,227 | 919,367 | 2,366,881 | 3,588,497 | 10,113,037 | 111,243,407 |
| -1 | -11 | -31 | -47 | -121 | -341 | -517 | -631 | -1,457 | -3,751 | -5,687 | -6,941 | -16,027 | -19,561 | -29,657 | -76,351 | -176,297 | -215,171 | -326,227 | -919,367 | -2,366,881 | -3,588,497 | -10,113,037 | -111,243,407 |
