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 16,600,265, 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 | 16,600,265 | |
| -1 | -16,600,265 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 16,600,265.
Example:
1 x 16,600,265 = 16,600,265
and
-1 x -16,600,265 = 16,600,265
Notice both answers equal 16,600,265
With that explanation out of the way, let's continue. Next, we take the number 16,600,265 and divide it by 2:
16,600,265 ÷ 2 = 8,300,132.5
If the quotient is a whole number, then 2 and 8,300,132.5 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 | 16,600,265 | |
| -1 | -16,600,265 |
Now, we try dividing 16,600,265 by 3:
16,600,265 ÷ 3 = 5,533,421.6667
If the quotient is a whole number, then 3 and 5,533,421.6667 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 | 16,600,265 | |
| -1 | -16,600,265 |
Let's try dividing by 4:
16,600,265 ÷ 4 = 4,150,066.25
If the quotient is a whole number, then 4 and 4,150,066.25 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 | 16,600,265 | |
| -1 | 16,600,265 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 113 | 565 | 1,243 | 2,671 | 6,215 | 13,355 | 29,381 | 146,905 | 301,823 | 1,509,115 | 3,320,053 | 16,600,265 |
| -1 | -5 | -11 | -55 | -113 | -565 | -1,243 | -2,671 | -6,215 | -13,355 | -29,381 | -146,905 | -301,823 | -1,509,115 | -3,320,053 | -16,600,265 |
