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 111,443,299, 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 | 111,443,299 | |
| -1 | -111,443,299 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 111,443,299.
Example:
1 x 111,443,299 = 111,443,299
and
-1 x -111,443,299 = 111,443,299
Notice both answers equal 111,443,299
With that explanation out of the way, let's continue. Next, we take the number 111,443,299 and divide it by 2:
111,443,299 ÷ 2 = 55,721,649.5
If the quotient is a whole number, then 2 and 55,721,649.5 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 | 111,443,299 | |
| -1 | -111,443,299 |
Now, we try dividing 111,443,299 by 3:
111,443,299 ÷ 3 = 37,147,766.3333
If the quotient is a whole number, then 3 and 37,147,766.3333 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 | 111,443,299 | |
| -1 | -111,443,299 |
Let's try dividing by 4:
111,443,299 ÷ 4 = 27,860,824.75
If the quotient is a whole number, then 4 and 27,860,824.75 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 | 111,443,299 | |
| -1 | 111,443,299 |
If you did it right, you will end up with this table:
| 1 | 11 | 101 | 121 | 829 | 1,111 | 1,331 | 9,119 | 12,221 | 83,729 | 100,309 | 134,431 | 921,019 | 1,103,399 | 10,131,209 | 111,443,299 |
| -1 | -11 | -101 | -121 | -829 | -1,111 | -1,331 | -9,119 | -12,221 | -83,729 | -100,309 | -134,431 | -921,019 | -1,103,399 | -10,131,209 | -111,443,299 |
