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 16,737,119, 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 | 16,737,119 | |
| -1 | -16,737,119 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 16,737,119.
Example:
1 x 16,737,119 = 16,737,119
and
-1 x -16,737,119 = 16,737,119
Notice both answers equal 16,737,119
With that explanation out of the way, let's continue. Next, we take the number 16,737,119 and divide it by 2:
16,737,119 ÷ 2 = 8,368,559.5
If the quotient is a whole number, then 2 and 8,368,559.5 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 | 16,737,119 | |
| -1 | -16,737,119 |
Now, we try dividing 16,737,119 by 3:
16,737,119 ÷ 3 = 5,579,039.6667
If the quotient is a whole number, then 3 and 5,579,039.6667 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 | 16,737,119 | |
| -1 | -16,737,119 |
Let's try dividing by 4:
16,737,119 ÷ 4 = 4,184,279.75
If the quotient is a whole number, then 4 and 4,184,279.75 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 | 16,737,119 | |
| -1 | 16,737,119 |
If you did it right, you will end up with this table:
| 1 | 7 | 19 | 61 | 133 | 427 | 1,159 | 2,063 | 8,113 | 14,441 | 39,197 | 125,843 | 274,379 | 880,901 | 2,391,017 | 16,737,119 |
| -1 | -7 | -19 | -61 | -133 | -427 | -1,159 | -2,063 | -8,113 | -14,441 | -39,197 | -125,843 | -274,379 | -880,901 | -2,391,017 | -16,737,119 |
