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 16,040,299, 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 | 16,040,299 | |
| -1 | -16,040,299 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 16,040,299.
Example:
1 x 16,040,299 = 16,040,299
and
-1 x -16,040,299 = 16,040,299
Notice both answers equal 16,040,299
With that explanation out of the way, let's continue. Next, we take the number 16,040,299 and divide it by 2:
16,040,299 ÷ 2 = 8,020,149.5
If the quotient is a whole number, then 2 and 8,020,149.5 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 | 16,040,299 | |
| -1 | -16,040,299 |
Now, we try dividing 16,040,299 by 3:
16,040,299 ÷ 3 = 5,346,766.3333
If the quotient is a whole number, then 3 and 5,346,766.3333 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 | 16,040,299 | |
| -1 | -16,040,299 |
Let's try dividing by 4:
16,040,299 ÷ 4 = 4,010,074.75
If the quotient is a whole number, then 4 and 4,010,074.75 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 | 16,040,299 | |
| -1 | 16,040,299 |
If you did it right, you will end up with this table:
| 1 | 11 | 17 | 31 | 187 | 341 | 527 | 2,767 | 5,797 | 30,437 | 47,039 | 85,777 | 517,429 | 943,547 | 1,458,209 | 16,040,299 |
| -1 | -11 | -17 | -31 | -187 | -341 | -527 | -2,767 | -5,797 | -30,437 | -47,039 | -85,777 | -517,429 | -943,547 | -1,458,209 | -16,040,299 |
