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 112,003,031, 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 | 112,003,031 | |
| -1 | -112,003,031 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 112,003,031.
Example:
1 x 112,003,031 = 112,003,031
and
-1 x -112,003,031 = 112,003,031
Notice both answers equal 112,003,031
With that explanation out of the way, let's continue. Next, we take the number 112,003,031 and divide it by 2:
112,003,031 ÷ 2 = 56,001,515.5
If the quotient is a whole number, then 2 and 56,001,515.5 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 | 112,003,031 | |
| -1 | -112,003,031 |
Now, we try dividing 112,003,031 by 3:
112,003,031 ÷ 3 = 37,334,343.6667
If the quotient is a whole number, then 3 and 37,334,343.6667 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 | 112,003,031 | |
| -1 | -112,003,031 |
Let's try dividing by 4:
112,003,031 ÷ 4 = 28,000,757.75
If the quotient is a whole number, then 4 and 28,000,757.75 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 | 112,003,031 | |
| -1 | 112,003,031 |
If you did it right, you will end up with this table:
| 1 | 7 | 23 | 31 | 161 | 217 | 713 | 4,991 | 22,441 | 157,087 | 516,143 | 695,671 | 3,613,001 | 4,869,697 | 16,000,433 | 112,003,031 |
| -1 | -7 | -23 | -31 | -161 | -217 | -713 | -4,991 | -22,441 | -157,087 | -516,143 | -695,671 | -3,613,001 | -4,869,697 | -16,000,433 | -112,003,031 |
