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 165,112,115, 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 | 165,112,115 | |
| -1 | -165,112,115 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 165,112,115.
Example:
1 x 165,112,115 = 165,112,115
and
-1 x -165,112,115 = 165,112,115
Notice both answers equal 165,112,115
With that explanation out of the way, let's continue. Next, we take the number 165,112,115 and divide it by 2:
165,112,115 ÷ 2 = 82,556,057.5
If the quotient is a whole number, then 2 and 82,556,057.5 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 | 165,112,115 | |
| -1 | -165,112,115 |
Now, we try dividing 165,112,115 by 3:
165,112,115 ÷ 3 = 55,037,371.6667
If the quotient is a whole number, then 3 and 55,037,371.6667 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 | 165,112,115 | |
| -1 | -165,112,115 |
Let's try dividing by 4:
165,112,115 ÷ 4 = 41,278,028.75
If the quotient is a whole number, then 4 and 41,278,028.75 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 | 165,112,115 | |
| -1 | 165,112,115 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 49 | 149 | 245 | 745 | 1,043 | 4,523 | 5,215 | 7,301 | 22,615 | 31,661 | 36,505 | 158,305 | 221,627 | 673,927 | 1,108,135 | 3,369,635 | 4,717,489 | 23,587,445 | 33,022,423 | 165,112,115 |
| -1 | -5 | -7 | -35 | -49 | -149 | -245 | -745 | -1,043 | -4,523 | -5,215 | -7,301 | -22,615 | -31,661 | -36,505 | -158,305 | -221,627 | -673,927 | -1,108,135 | -3,369,635 | -4,717,489 | -23,587,445 | -33,022,423 | -165,112,115 |
