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 39,259,375, 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 | 39,259,375 | |
| -1 | -39,259,375 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 39,259,375.
Example:
1 x 39,259,375 = 39,259,375
and
-1 x -39,259,375 = 39,259,375
Notice both answers equal 39,259,375
With that explanation out of the way, let's continue. Next, we take the number 39,259,375 and divide it by 2:
39,259,375 ÷ 2 = 19,629,687.5
If the quotient is a whole number, then 2 and 19,629,687.5 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 | 39,259,375 | |
| -1 | -39,259,375 |
Now, we try dividing 39,259,375 by 3:
39,259,375 ÷ 3 = 13,086,458.3333
If the quotient is a whole number, then 3 and 13,086,458.3333 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 | 39,259,375 | |
| -1 | -39,259,375 |
Let's try dividing by 4:
39,259,375 ÷ 4 = 9,814,843.75
If the quotient is a whole number, then 4 and 9,814,843.75 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 | 39,259,375 | |
| -1 | 39,259,375 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 25 | 85 | 125 | 425 | 625 | 739 | 2,125 | 3,125 | 3,695 | 10,625 | 12,563 | 18,475 | 53,125 | 62,815 | 92,375 | 314,075 | 461,875 | 1,570,375 | 2,309,375 | 7,851,875 | 39,259,375 |
| -1 | -5 | -17 | -25 | -85 | -125 | -425 | -625 | -739 | -2,125 | -3,125 | -3,695 | -10,625 | -12,563 | -18,475 | -53,125 | -62,815 | -92,375 | -314,075 | -461,875 | -1,570,375 | -2,309,375 | -7,851,875 | -39,259,375 |
