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 112,160,719, 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 | 112,160,719 | |
| -1 | -112,160,719 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 112,160,719.
Example:
1 x 112,160,719 = 112,160,719
and
-1 x -112,160,719 = 112,160,719
Notice both answers equal 112,160,719
With that explanation out of the way, let's continue. Next, we take the number 112,160,719 and divide it by 2:
112,160,719 ÷ 2 = 56,080,359.5
If the quotient is a whole number, then 2 and 56,080,359.5 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 | 112,160,719 | |
| -1 | -112,160,719 |
Now, we try dividing 112,160,719 by 3:
112,160,719 ÷ 3 = 37,386,906.3333
If the quotient is a whole number, then 3 and 37,386,906.3333 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 | 112,160,719 | |
| -1 | -112,160,719 |
Let's try dividing by 4:
112,160,719 ÷ 4 = 28,040,179.75
If the quotient is a whole number, then 4 and 28,040,179.75 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 | 112,160,719 | |
| -1 | 112,160,719 |
If you did it right, you will end up with this table:
| 1 | 11 | 23 | 29 | 253 | 319 | 667 | 7,337 | 15,287 | 168,157 | 351,601 | 443,323 | 3,867,611 | 4,876,553 | 10,196,429 | 112,160,719 |
| -1 | -11 | -23 | -29 | -253 | -319 | -667 | -7,337 | -15,287 | -168,157 | -351,601 | -443,323 | -3,867,611 | -4,876,553 | -10,196,429 | -112,160,719 |
