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 111,433,231, 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 | 111,433,231 | |
| -1 | -111,433,231 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 111,433,231.
Example:
1 x 111,433,231 = 111,433,231
and
-1 x -111,433,231 = 111,433,231
Notice both answers equal 111,433,231
With that explanation out of the way, let's continue. Next, we take the number 111,433,231 and divide it by 2:
111,433,231 ÷ 2 = 55,716,615.5
If the quotient is a whole number, then 2 and 55,716,615.5 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 | 111,433,231 | |
| -1 | -111,433,231 |
Now, we try dividing 111,433,231 by 3:
111,433,231 ÷ 3 = 37,144,410.3333
If the quotient is a whole number, then 3 and 37,144,410.3333 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 | 111,433,231 | |
| -1 | -111,433,231 |
Let's try dividing by 4:
111,433,231 ÷ 4 = 27,858,307.75
If the quotient is a whole number, then 4 and 27,858,307.75 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 | 111,433,231 | |
| -1 | 111,433,231 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 91 | 283 | 1,981 | 3,679 | 4,327 | 25,753 | 30,289 | 56,251 | 393,757 | 1,224,541 | 8,571,787 | 15,919,033 | 111,433,231 |
| -1 | -7 | -13 | -91 | -283 | -1,981 | -3,679 | -4,327 | -25,753 | -30,289 | -56,251 | -393,757 | -1,224,541 | -8,571,787 | -15,919,033 | -111,433,231 |
