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 16,714,915, 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 | 16,714,915 | |
| -1 | -16,714,915 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 16,714,915.
Example:
1 x 16,714,915 = 16,714,915
and
-1 x -16,714,915 = 16,714,915
Notice both answers equal 16,714,915
With that explanation out of the way, let's continue. Next, we take the number 16,714,915 and divide it by 2:
16,714,915 ÷ 2 = 8,357,457.5
If the quotient is a whole number, then 2 and 8,357,457.5 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 | 16,714,915 | |
| -1 | -16,714,915 |
Now, we try dividing 16,714,915 by 3:
16,714,915 ÷ 3 = 5,571,638.3333
If the quotient is a whole number, then 3 and 5,571,638.3333 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 | 16,714,915 | |
| -1 | -16,714,915 |
Let's try dividing by 4:
16,714,915 ÷ 4 = 4,178,728.75
If the quotient is a whole number, then 4 and 4,178,728.75 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 | 16,714,915 | |
| -1 | 16,714,915 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 61 | 305 | 427 | 2,135 | 7,829 | 39,145 | 54,803 | 274,015 | 477,569 | 2,387,845 | 3,342,983 | 16,714,915 |
| -1 | -5 | -7 | -35 | -61 | -305 | -427 | -2,135 | -7,829 | -39,145 | -54,803 | -274,015 | -477,569 | -2,387,845 | -3,342,983 | -16,714,915 |
