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 15,614,027, 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 | 15,614,027 | |
| -1 | -15,614,027 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 15,614,027.
Example:
1 x 15,614,027 = 15,614,027
and
-1 x -15,614,027 = 15,614,027
Notice both answers equal 15,614,027
With that explanation out of the way, let's continue. Next, we take the number 15,614,027 and divide it by 2:
15,614,027 ÷ 2 = 7,807,013.5
If the quotient is a whole number, then 2 and 7,807,013.5 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 | 15,614,027 | |
| -1 | -15,614,027 |
Now, we try dividing 15,614,027 by 3:
15,614,027 ÷ 3 = 5,204,675.6667
If the quotient is a whole number, then 3 and 5,204,675.6667 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 | 15,614,027 | |
| -1 | -15,614,027 |
Let's try dividing by 4:
15,614,027 ÷ 4 = 3,903,506.75
If the quotient is a whole number, then 4 and 3,903,506.75 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 | 15,614,027 | |
| -1 | 15,614,027 |
If you did it right, you will end up with this table:
| 1 | 11 | 13 | 137 | 143 | 797 | 1,507 | 1,781 | 8,767 | 10,361 | 19,591 | 109,189 | 113,971 | 1,201,079 | 1,419,457 | 15,614,027 |
| -1 | -11 | -13 | -137 | -143 | -797 | -1,507 | -1,781 | -8,767 | -10,361 | -19,591 | -109,189 | -113,971 | -1,201,079 | -1,419,457 | -15,614,027 |
