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 16,002,107, 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 | 16,002,107 | |
| -1 | -16,002,107 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 16,002,107.
Example:
1 x 16,002,107 = 16,002,107
and
-1 x -16,002,107 = 16,002,107
Notice both answers equal 16,002,107
With that explanation out of the way, let's continue. Next, we take the number 16,002,107 and divide it by 2:
16,002,107 ÷ 2 = 8,001,053.5
If the quotient is a whole number, then 2 and 8,001,053.5 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 | 16,002,107 | |
| -1 | -16,002,107 |
Now, we try dividing 16,002,107 by 3:
16,002,107 ÷ 3 = 5,334,035.6667
If the quotient is a whole number, then 3 and 5,334,035.6667 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 | 16,002,107 | |
| -1 | -16,002,107 |
Let's try dividing by 4:
16,002,107 ÷ 4 = 4,000,526.75
If the quotient is a whole number, then 4 and 4,000,526.75 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 | 16,002,107 | |
| -1 | 16,002,107 |
If you did it right, you will end up with this table:
| 1 | 11 | 31 | 167 | 281 | 341 | 1,837 | 3,091 | 5,177 | 8,711 | 46,927 | 56,947 | 95,821 | 516,197 | 1,454,737 | 16,002,107 |
| -1 | -11 | -31 | -167 | -281 | -341 | -1,837 | -3,091 | -5,177 | -8,711 | -46,927 | -56,947 | -95,821 | -516,197 | -1,454,737 | -16,002,107 |
