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 112,443,331, 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 | 112,443,331 | |
| -1 | -112,443,331 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 112,443,331.
Example:
1 x 112,443,331 = 112,443,331
and
-1 x -112,443,331 = 112,443,331
Notice both answers equal 112,443,331
With that explanation out of the way, let's continue. Next, we take the number 112,443,331 and divide it by 2:
112,443,331 ÷ 2 = 56,221,665.5
If the quotient is a whole number, then 2 and 56,221,665.5 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 | 112,443,331 | |
| -1 | -112,443,331 |
Now, we try dividing 112,443,331 by 3:
112,443,331 ÷ 3 = 37,481,110.3333
If the quotient is a whole number, then 3 and 37,481,110.3333 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 | 112,443,331 | |
| -1 | -112,443,331 |
Let's try dividing by 4:
112,443,331 ÷ 4 = 28,110,832.75
If the quotient is a whole number, then 4 and 28,110,832.75 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 | 112,443,331 | |
| -1 | 112,443,331 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 13 | 77 | 91 | 143 | 1,001 | 112,331 | 786,317 | 1,235,641 | 1,460,303 | 8,649,487 | 10,222,121 | 16,063,333 | 112,443,331 |
| -1 | -7 | -11 | -13 | -77 | -91 | -143 | -1,001 | -112,331 | -786,317 | -1,235,641 | -1,460,303 | -8,649,487 | -10,222,121 | -16,063,333 | -112,443,331 |
