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 21,667,375, 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 | 21,667,375 | |
| -1 | -21,667,375 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 21,667,375.
Example:
1 x 21,667,375 = 21,667,375
and
-1 x -21,667,375 = 21,667,375
Notice both answers equal 21,667,375
With that explanation out of the way, let's continue. Next, we take the number 21,667,375 and divide it by 2:
21,667,375 ÷ 2 = 10,833,687.5
If the quotient is a whole number, then 2 and 10,833,687.5 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 | 21,667,375 | |
| -1 | -21,667,375 |
Now, we try dividing 21,667,375 by 3:
21,667,375 ÷ 3 = 7,222,458.3333
If the quotient is a whole number, then 3 and 7,222,458.3333 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 | 21,667,375 | |
| -1 | -21,667,375 |
Let's try dividing by 4:
21,667,375 ÷ 4 = 5,416,843.75
If the quotient is a whole number, then 4 and 5,416,843.75 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 | 21,667,375 | |
| -1 | 21,667,375 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 97 | 125 | 485 | 1,787 | 2,425 | 8,935 | 12,125 | 44,675 | 173,339 | 223,375 | 866,695 | 4,333,475 | 21,667,375 |
| -1 | -5 | -25 | -97 | -125 | -485 | -1,787 | -2,425 | -8,935 | -12,125 | -44,675 | -173,339 | -223,375 | -866,695 | -4,333,475 | -21,667,375 |
