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 40,322,125, 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 | 40,322,125 | |
| -1 | -40,322,125 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 40,322,125.
Example:
1 x 40,322,125 = 40,322,125
and
-1 x -40,322,125 = 40,322,125
Notice both answers equal 40,322,125
With that explanation out of the way, let's continue. Next, we take the number 40,322,125 and divide it by 2:
40,322,125 ÷ 2 = 20,161,062.5
If the quotient is a whole number, then 2 and 20,161,062.5 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 | 40,322,125 | |
| -1 | -40,322,125 |
Now, we try dividing 40,322,125 by 3:
40,322,125 ÷ 3 = 13,440,708.3333
If the quotient is a whole number, then 3 and 13,440,708.3333 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 | 40,322,125 | |
| -1 | -40,322,125 |
Let's try dividing by 4:
40,322,125 ÷ 4 = 10,080,531.25
If the quotient is a whole number, then 4 and 10,080,531.25 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 | 40,322,125 | |
| -1 | 40,322,125 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 125 | 163 | 815 | 1,979 | 4,075 | 9,895 | 20,375 | 49,475 | 247,375 | 322,577 | 1,612,885 | 8,064,425 | 40,322,125 |
| -1 | -5 | -25 | -125 | -163 | -815 | -1,979 | -4,075 | -9,895 | -20,375 | -49,475 | -247,375 | -322,577 | -1,612,885 | -8,064,425 | -40,322,125 |
