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 16,262,755, 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 | 16,262,755 | |
| -1 | -16,262,755 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 16,262,755.
Example:
1 x 16,262,755 = 16,262,755
and
-1 x -16,262,755 = 16,262,755
Notice both answers equal 16,262,755
With that explanation out of the way, let's continue. Next, we take the number 16,262,755 and divide it by 2:
16,262,755 ÷ 2 = 8,131,377.5
If the quotient is a whole number, then 2 and 8,131,377.5 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 | 16,262,755 | |
| -1 | -16,262,755 |
Now, we try dividing 16,262,755 by 3:
16,262,755 ÷ 3 = 5,420,918.3333
If the quotient is a whole number, then 3 and 5,420,918.3333 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 | 16,262,755 | |
| -1 | -16,262,755 |
Let's try dividing by 4:
16,262,755 ÷ 4 = 4,065,688.75
If the quotient is a whole number, then 4 and 4,065,688.75 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 | 16,262,755 | |
| -1 | 16,262,755 |
If you did it right, you will end up with this table:
| 1 | 5 | 31 | 155 | 239 | 439 | 1,195 | 2,195 | 7,409 | 13,609 | 37,045 | 68,045 | 104,921 | 524,605 | 3,252,551 | 16,262,755 |
| -1 | -5 | -31 | -155 | -239 | -439 | -1,195 | -2,195 | -7,409 | -13,609 | -37,045 | -68,045 | -104,921 | -524,605 | -3,252,551 | -16,262,755 |
