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 16,731,835, 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 | 16,731,835 | |
| -1 | -16,731,835 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 16,731,835.
Example:
1 x 16,731,835 = 16,731,835
and
-1 x -16,731,835 = 16,731,835
Notice both answers equal 16,731,835
With that explanation out of the way, let's continue. Next, we take the number 16,731,835 and divide it by 2:
16,731,835 ÷ 2 = 8,365,917.5
If the quotient is a whole number, then 2 and 8,365,917.5 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 | 16,731,835 | |
| -1 | -16,731,835 |
Now, we try dividing 16,731,835 by 3:
16,731,835 ÷ 3 = 5,577,278.3333
If the quotient is a whole number, then 3 and 5,577,278.3333 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 | 16,731,835 | |
| -1 | -16,731,835 |
Let's try dividing by 4:
16,731,835 ÷ 4 = 4,182,958.75
If the quotient is a whole number, then 4 and 4,182,958.75 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 | 16,731,835 | |
| -1 | 16,731,835 |
If you did it right, you will end up with this table:
| 1 | 5 | 53 | 103 | 265 | 515 | 613 | 3,065 | 5,459 | 27,295 | 32,489 | 63,139 | 162,445 | 315,695 | 3,346,367 | 16,731,835 |
| -1 | -5 | -53 | -103 | -265 | -515 | -613 | -3,065 | -5,459 | -27,295 | -32,489 | -63,139 | -162,445 | -315,695 | -3,346,367 | -16,731,835 |
