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 16,903,579, 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 | 16,903,579 | |
| -1 | -16,903,579 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 16,903,579.
Example:
1 x 16,903,579 = 16,903,579
and
-1 x -16,903,579 = 16,903,579
Notice both answers equal 16,903,579
With that explanation out of the way, let's continue. Next, we take the number 16,903,579 and divide it by 2:
16,903,579 ÷ 2 = 8,451,789.5
If the quotient is a whole number, then 2 and 8,451,789.5 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 | 16,903,579 | |
| -1 | -16,903,579 |
Now, we try dividing 16,903,579 by 3:
16,903,579 ÷ 3 = 5,634,526.3333
If the quotient is a whole number, then 3 and 5,634,526.3333 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 | 16,903,579 | |
| -1 | -16,903,579 |
Let's try dividing by 4:
16,903,579 ÷ 4 = 4,225,894.75
If the quotient is a whole number, then 4 and 4,225,894.75 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 | 16,903,579 | |
| -1 | 16,903,579 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 49 | 77 | 121 | 539 | 847 | 2,851 | 5,929 | 19,957 | 31,361 | 139,699 | 219,527 | 344,971 | 1,536,689 | 2,414,797 | 16,903,579 |
| -1 | -7 | -11 | -49 | -77 | -121 | -539 | -847 | -2,851 | -5,929 | -19,957 | -31,361 | -139,699 | -219,527 | -344,971 | -1,536,689 | -2,414,797 | -16,903,579 |
