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 112,202,113, 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 | 112,202,113 | |
| -1 | -112,202,113 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 112,202,113.
Example:
1 x 112,202,113 = 112,202,113
and
-1 x -112,202,113 = 112,202,113
Notice both answers equal 112,202,113
With that explanation out of the way, let's continue. Next, we take the number 112,202,113 and divide it by 2:
112,202,113 ÷ 2 = 56,101,056.5
If the quotient is a whole number, then 2 and 56,101,056.5 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 | 112,202,113 | |
| -1 | -112,202,113 |
Now, we try dividing 112,202,113 by 3:
112,202,113 ÷ 3 = 37,400,704.3333
If the quotient is a whole number, then 3 and 37,400,704.3333 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 | 112,202,113 | |
| -1 | -112,202,113 |
Let's try dividing by 4:
112,202,113 ÷ 4 = 28,050,528.25
If the quotient is a whole number, then 4 and 28,050,528.25 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 | 112,202,113 | |
| -1 | 112,202,113 |
If you did it right, you will end up with this table:
| 1 | 31 | 47 | 53 | 1,453 | 1,457 | 1,643 | 2,491 | 45,043 | 68,291 | 77,009 | 77,221 | 2,117,021 | 2,387,279 | 3,619,423 | 112,202,113 |
| -1 | -31 | -47 | -53 | -1,453 | -1,457 | -1,643 | -2,491 | -45,043 | -68,291 | -77,009 | -77,221 | -2,117,021 | -2,387,279 | -3,619,423 | -112,202,113 |
