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 40,248,125, 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 | 40,248,125 | |
| -1 | -40,248,125 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 40,248,125.
Example:
1 x 40,248,125 = 40,248,125
and
-1 x -40,248,125 = 40,248,125
Notice both answers equal 40,248,125
With that explanation out of the way, let's continue. Next, we take the number 40,248,125 and divide it by 2:
40,248,125 ÷ 2 = 20,124,062.5
If the quotient is a whole number, then 2 and 20,124,062.5 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 | 40,248,125 | |
| -1 | -40,248,125 |
Now, we try dividing 40,248,125 by 3:
40,248,125 ÷ 3 = 13,416,041.6667
If the quotient is a whole number, then 3 and 13,416,041.6667 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 | 40,248,125 | |
| -1 | -40,248,125 |
Let's try dividing by 4:
40,248,125 ÷ 4 = 10,062,031.25
If the quotient is a whole number, then 4 and 10,062,031.25 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 | 40,248,125 | |
| -1 | 40,248,125 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 71 | 125 | 355 | 625 | 907 | 1,775 | 4,535 | 8,875 | 22,675 | 44,375 | 64,397 | 113,375 | 321,985 | 566,875 | 1,609,925 | 8,049,625 | 40,248,125 |
| -1 | -5 | -25 | -71 | -125 | -355 | -625 | -907 | -1,775 | -4,535 | -8,875 | -22,675 | -44,375 | -64,397 | -113,375 | -321,985 | -566,875 | -1,609,925 | -8,049,625 | -40,248,125 |
