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 16,336,865, 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 | 16,336,865 | |
| -1 | -16,336,865 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 16,336,865.
Example:
1 x 16,336,865 = 16,336,865
and
-1 x -16,336,865 = 16,336,865
Notice both answers equal 16,336,865
With that explanation out of the way, let's continue. Next, we take the number 16,336,865 and divide it by 2:
16,336,865 ÷ 2 = 8,168,432.5
If the quotient is a whole number, then 2 and 8,168,432.5 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 | 16,336,865 | |
| -1 | -16,336,865 |
Now, we try dividing 16,336,865 by 3:
16,336,865 ÷ 3 = 5,445,621.6667
If the quotient is a whole number, then 3 and 5,445,621.6667 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 | 16,336,865 | |
| -1 | -16,336,865 |
Let's try dividing by 4:
16,336,865 ÷ 4 = 4,084,216.25
If the quotient is a whole number, then 4 and 4,084,216.25 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 | 16,336,865 | |
| -1 | 16,336,865 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 95 | 383 | 449 | 1,915 | 2,245 | 7,277 | 8,531 | 36,385 | 42,655 | 171,967 | 859,835 | 3,267,373 | 16,336,865 |
| -1 | -5 | -19 | -95 | -383 | -449 | -1,915 | -2,245 | -7,277 | -8,531 | -36,385 | -42,655 | -171,967 | -859,835 | -3,267,373 | -16,336,865 |
