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 112,726,427, 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 | 112,726,427 | |
| -1 | -112,726,427 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 112,726,427.
Example:
1 x 112,726,427 = 112,726,427
and
-1 x -112,726,427 = 112,726,427
Notice both answers equal 112,726,427
With that explanation out of the way, let's continue. Next, we take the number 112,726,427 and divide it by 2:
112,726,427 ÷ 2 = 56,363,213.5
If the quotient is a whole number, then 2 and 56,363,213.5 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 | 112,726,427 | |
| -1 | -112,726,427 |
Now, we try dividing 112,726,427 by 3:
112,726,427 ÷ 3 = 37,575,475.6667
If the quotient is a whole number, then 3 and 37,575,475.6667 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 | 112,726,427 | |
| -1 | -112,726,427 |
Let's try dividing by 4:
112,726,427 ÷ 4 = 28,181,606.75
If the quotient is a whole number, then 4 and 28,181,606.75 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 | 112,726,427 | |
| -1 | 112,726,427 |
If you did it right, you will end up with this table:
| 1 | 11 | 23 | 113 | 253 | 1,243 | 2,599 | 3,943 | 28,589 | 43,373 | 90,689 | 445,559 | 997,579 | 4,901,149 | 10,247,857 | 112,726,427 |
| -1 | -11 | -23 | -113 | -253 | -1,243 | -2,599 | -3,943 | -28,589 | -43,373 | -90,689 | -445,559 | -997,579 | -4,901,149 | -10,247,857 | -112,726,427 |
