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 20,141,375, 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 | 20,141,375 | |
| -1 | -20,141,375 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 20,141,375.
Example:
1 x 20,141,375 = 20,141,375
and
-1 x -20,141,375 = 20,141,375
Notice both answers equal 20,141,375
With that explanation out of the way, let's continue. Next, we take the number 20,141,375 and divide it by 2:
20,141,375 ÷ 2 = 10,070,687.5
If the quotient is a whole number, then 2 and 10,070,687.5 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 | 20,141,375 | |
| -1 | -20,141,375 |
Now, we try dividing 20,141,375 by 3:
20,141,375 ÷ 3 = 6,713,791.6667
If the quotient is a whole number, then 3 and 6,713,791.6667 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 | 20,141,375 | |
| -1 | -20,141,375 |
Let's try dividing by 4:
20,141,375 ÷ 4 = 5,035,343.75
If the quotient is a whole number, then 4 and 5,035,343.75 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 | 20,141,375 | |
| -1 | 20,141,375 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 125 | 269 | 599 | 1,345 | 2,995 | 6,725 | 14,975 | 33,625 | 74,875 | 161,131 | 805,655 | 4,028,275 | 20,141,375 |
| -1 | -5 | -25 | -125 | -269 | -599 | -1,345 | -2,995 | -6,725 | -14,975 | -33,625 | -74,875 | -161,131 | -805,655 | -4,028,275 | -20,141,375 |
