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 20,014,127, 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 | 20,014,127 | |
| -1 | -20,014,127 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 20,014,127.
Example:
1 x 20,014,127 = 20,014,127
and
-1 x -20,014,127 = 20,014,127
Notice both answers equal 20,014,127
With that explanation out of the way, let's continue. Next, we take the number 20,014,127 and divide it by 2:
20,014,127 ÷ 2 = 10,007,063.5
If the quotient is a whole number, then 2 and 10,007,063.5 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 | 20,014,127 | |
| -1 | -20,014,127 |
Now, we try dividing 20,014,127 by 3:
20,014,127 ÷ 3 = 6,671,375.6667
If the quotient is a whole number, then 3 and 6,671,375.6667 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 | 20,014,127 | |
| -1 | -20,014,127 |
Let's try dividing by 4:
20,014,127 ÷ 4 = 5,003,531.75
If the quotient is a whole number, then 4 and 5,003,531.75 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 | 20,014,127 | |
| -1 | 20,014,127 |
If you did it right, you will end up with this table:
| 1 | 7 | 31 | 149 | 217 | 619 | 1,043 | 4,333 | 4,619 | 19,189 | 32,333 | 92,231 | 134,323 | 645,617 | 2,859,161 | 20,014,127 |
| -1 | -7 | -31 | -149 | -217 | -619 | -1,043 | -4,333 | -4,619 | -19,189 | -32,333 | -92,231 | -134,323 | -645,617 | -2,859,161 | -20,014,127 |
