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 20,046,767, 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 | 20,046,767 | |
| -1 | -20,046,767 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 20,046,767.
Example:
1 x 20,046,767 = 20,046,767
and
-1 x -20,046,767 = 20,046,767
Notice both answers equal 20,046,767
With that explanation out of the way, let's continue. Next, we take the number 20,046,767 and divide it by 2:
20,046,767 ÷ 2 = 10,023,383.5
If the quotient is a whole number, then 2 and 10,023,383.5 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 | 20,046,767 | |
| -1 | -20,046,767 |
Now, we try dividing 20,046,767 by 3:
20,046,767 ÷ 3 = 6,682,255.6667
If the quotient is a whole number, then 3 and 6,682,255.6667 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 | 20,046,767 | |
| -1 | -20,046,767 |
Let's try dividing by 4:
20,046,767 ÷ 4 = 5,011,691.75
If the quotient is a whole number, then 4 and 5,011,691.75 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 | 20,046,767 | |
| -1 | 20,046,767 |
If you did it right, you will end up with this table:
| 1 | 13 | 19 | 247 | 277 | 293 | 3,601 | 3,809 | 5,263 | 5,567 | 68,419 | 72,371 | 81,161 | 1,055,093 | 1,542,059 | 20,046,767 |
| -1 | -13 | -19 | -247 | -277 | -293 | -3,601 | -3,809 | -5,263 | -5,567 | -68,419 | -72,371 | -81,161 | -1,055,093 | -1,542,059 | -20,046,767 |
