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 16,156,255, 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 | 16,156,255 | |
| -1 | -16,156,255 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 16,156,255.
Example:
1 x 16,156,255 = 16,156,255
and
-1 x -16,156,255 = 16,156,255
Notice both answers equal 16,156,255
With that explanation out of the way, let's continue. Next, we take the number 16,156,255 and divide it by 2:
16,156,255 ÷ 2 = 8,078,127.5
If the quotient is a whole number, then 2 and 8,078,127.5 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 | 16,156,255 | |
| -1 | -16,156,255 |
Now, we try dividing 16,156,255 by 3:
16,156,255 ÷ 3 = 5,385,418.3333
If the quotient is a whole number, then 3 and 5,385,418.3333 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 | 16,156,255 | |
| -1 | -16,156,255 |
Let's try dividing by 4:
16,156,255 ÷ 4 = 4,039,063.75
If the quotient is a whole number, then 4 and 4,039,063.75 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 | 16,156,255 | |
| -1 | 16,156,255 |
If you did it right, you will end up with this table:
| 1 | 5 | 41 | 53 | 205 | 265 | 1,487 | 2,173 | 7,435 | 10,865 | 60,967 | 78,811 | 304,835 | 394,055 | 3,231,251 | 16,156,255 |
| -1 | -5 | -41 | -53 | -205 | -265 | -1,487 | -2,173 | -7,435 | -10,865 | -60,967 | -78,811 | -304,835 | -394,055 | -3,231,251 | -16,156,255 |
