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 16,286,501, 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 | 16,286,501 | |
| -1 | -16,286,501 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 16,286,501.
Example:
1 x 16,286,501 = 16,286,501
and
-1 x -16,286,501 = 16,286,501
Notice both answers equal 16,286,501
With that explanation out of the way, let's continue. Next, we take the number 16,286,501 and divide it by 2:
16,286,501 ÷ 2 = 8,143,250.5
If the quotient is a whole number, then 2 and 8,143,250.5 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 | 16,286,501 | |
| -1 | -16,286,501 |
Now, we try dividing 16,286,501 by 3:
16,286,501 ÷ 3 = 5,428,833.6667
If the quotient is a whole number, then 3 and 5,428,833.6667 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 | 16,286,501 | |
| -1 | -16,286,501 |
Let's try dividing by 4:
16,286,501 ÷ 4 = 4,071,625.25
If the quotient is a whole number, then 4 and 4,071,625.25 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 | 16,286,501 | |
| -1 | 16,286,501 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 31 | 77 | 217 | 341 | 2,387 | 6,823 | 47,761 | 75,053 | 211,513 | 525,371 | 1,480,591 | 2,326,643 | 16,286,501 |
| -1 | -7 | -11 | -31 | -77 | -217 | -341 | -2,387 | -6,823 | -47,761 | -75,053 | -211,513 | -525,371 | -1,480,591 | -2,326,643 | -16,286,501 |
