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 16,078,825, 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 | 16,078,825 | |
| -1 | -16,078,825 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 16,078,825.
Example:
1 x 16,078,825 = 16,078,825
and
-1 x -16,078,825 = 16,078,825
Notice both answers equal 16,078,825
With that explanation out of the way, let's continue. Next, we take the number 16,078,825 and divide it by 2:
16,078,825 ÷ 2 = 8,039,412.5
If the quotient is a whole number, then 2 and 8,039,412.5 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 | 16,078,825 | |
| -1 | -16,078,825 |
Now, we try dividing 16,078,825 by 3:
16,078,825 ÷ 3 = 5,359,608.3333
If the quotient is a whole number, then 3 and 5,359,608.3333 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 | 16,078,825 | |
| -1 | -16,078,825 |
Let's try dividing by 4:
16,078,825 ÷ 4 = 4,019,706.25
If the quotient is a whole number, then 4 and 4,019,706.25 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 | 16,078,825 | |
| -1 | 16,078,825 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 25 | 35 | 139 | 175 | 661 | 695 | 973 | 3,305 | 3,475 | 4,627 | 4,865 | 16,525 | 23,135 | 24,325 | 91,879 | 115,675 | 459,395 | 643,153 | 2,296,975 | 3,215,765 | 16,078,825 |
| -1 | -5 | -7 | -25 | -35 | -139 | -175 | -661 | -695 | -973 | -3,305 | -3,475 | -4,627 | -4,865 | -16,525 | -23,135 | -24,325 | -91,879 | -115,675 | -459,395 | -643,153 | -2,296,975 | -3,215,765 | -16,078,825 |
