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 16,744,745, 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 | 16,744,745 | |
| -1 | -16,744,745 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 16,744,745.
Example:
1 x 16,744,745 = 16,744,745
and
-1 x -16,744,745 = 16,744,745
Notice both answers equal 16,744,745
With that explanation out of the way, let's continue. Next, we take the number 16,744,745 and divide it by 2:
16,744,745 ÷ 2 = 8,372,372.5
If the quotient is a whole number, then 2 and 8,372,372.5 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 | 16,744,745 | |
| -1 | -16,744,745 |
Now, we try dividing 16,744,745 by 3:
16,744,745 ÷ 3 = 5,581,581.6667
If the quotient is a whole number, then 3 and 5,581,581.6667 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 | 16,744,745 | |
| -1 | -16,744,745 |
Let's try dividing by 4:
16,744,745 ÷ 4 = 4,186,186.25
If the quotient is a whole number, then 4 and 4,186,186.25 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 | 16,744,745 | |
| -1 | 16,744,745 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 29 | 85 | 145 | 493 | 2,465 | 6,793 | 33,965 | 115,481 | 196,997 | 577,405 | 984,985 | 3,348,949 | 16,744,745 |
| -1 | -5 | -17 | -29 | -85 | -145 | -493 | -2,465 | -6,793 | -33,965 | -115,481 | -196,997 | -577,405 | -984,985 | -3,348,949 | -16,744,745 |
