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 165,149,375, 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 | 165,149,375 | |
| -1 | -165,149,375 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 165,149,375.
Example:
1 x 165,149,375 = 165,149,375
and
-1 x -165,149,375 = 165,149,375
Notice both answers equal 165,149,375
With that explanation out of the way, let's continue. Next, we take the number 165,149,375 and divide it by 2:
165,149,375 ÷ 2 = 82,574,687.5
If the quotient is a whole number, then 2 and 82,574,687.5 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 | 165,149,375 | |
| -1 | -165,149,375 |
Now, we try dividing 165,149,375 by 3:
165,149,375 ÷ 3 = 55,049,791.6667
If the quotient is a whole number, then 3 and 55,049,791.6667 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 | 165,149,375 | |
| -1 | -165,149,375 |
Let's try dividing by 4:
165,149,375 ÷ 4 = 41,287,343.75
If the quotient is a whole number, then 4 and 41,287,343.75 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 | 165,149,375 | |
| -1 | 165,149,375 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 125 | 139 | 625 | 695 | 1,901 | 3,475 | 9,505 | 17,375 | 47,525 | 86,875 | 237,625 | 264,239 | 1,188,125 | 1,321,195 | 6,605,975 | 33,029,875 | 165,149,375 |
| -1 | -5 | -25 | -125 | -139 | -625 | -695 | -1,901 | -3,475 | -9,505 | -17,375 | -47,525 | -86,875 | -237,625 | -264,239 | -1,188,125 | -1,321,195 | -6,605,975 | -33,029,875 | -165,149,375 |
