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 16,745,311, 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 | 16,745,311 | |
| -1 | -16,745,311 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 16,745,311.
Example:
1 x 16,745,311 = 16,745,311
and
-1 x -16,745,311 = 16,745,311
Notice both answers equal 16,745,311
With that explanation out of the way, let's continue. Next, we take the number 16,745,311 and divide it by 2:
16,745,311 ÷ 2 = 8,372,655.5
If the quotient is a whole number, then 2 and 8,372,655.5 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 | 16,745,311 | |
| -1 | -16,745,311 |
Now, we try dividing 16,745,311 by 3:
16,745,311 ÷ 3 = 5,581,770.3333
If the quotient is a whole number, then 3 and 5,581,770.3333 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 | 16,745,311 | |
| -1 | -16,745,311 |
Let's try dividing by 4:
16,745,311 ÷ 4 = 4,186,327.75
If the quotient is a whole number, then 4 and 4,186,327.75 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 | 16,745,311 | |
| -1 | 16,745,311 |
If you did it right, you will end up with this table:
| 1 | 11 | 23 | 121 | 253 | 547 | 1,331 | 2,783 | 6,017 | 12,581 | 30,613 | 66,187 | 138,391 | 728,057 | 1,522,301 | 16,745,311 |
| -1 | -11 | -23 | -121 | -253 | -547 | -1,331 | -2,783 | -6,017 | -12,581 | -30,613 | -66,187 | -138,391 | -728,057 | -1,522,301 | -16,745,311 |
