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 16,101,307, 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 | 16,101,307 | |
| -1 | -16,101,307 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 16,101,307.
Example:
1 x 16,101,307 = 16,101,307
and
-1 x -16,101,307 = 16,101,307
Notice both answers equal 16,101,307
With that explanation out of the way, let's continue. Next, we take the number 16,101,307 and divide it by 2:
16,101,307 ÷ 2 = 8,050,653.5
If the quotient is a whole number, then 2 and 8,050,653.5 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 | 16,101,307 | |
| -1 | -16,101,307 |
Now, we try dividing 16,101,307 by 3:
16,101,307 ÷ 3 = 5,367,102.3333
If the quotient is a whole number, then 3 and 5,367,102.3333 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 | 16,101,307 | |
| -1 | -16,101,307 |
Let's try dividing by 4:
16,101,307 ÷ 4 = 4,025,326.75
If the quotient is a whole number, then 4 and 4,025,326.75 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 | 16,101,307 | |
| -1 | 16,101,307 |
If you did it right, you will end up with this table:
| 1 | 31 | 43 | 47 | 257 | 1,333 | 1,457 | 2,021 | 7,967 | 11,051 | 12,079 | 62,651 | 342,581 | 374,449 | 519,397 | 16,101,307 |
| -1 | -31 | -43 | -47 | -257 | -1,333 | -1,457 | -2,021 | -7,967 | -11,051 | -12,079 | -62,651 | -342,581 | -374,449 | -519,397 | -16,101,307 |
