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 17,367,515, 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 | 17,367,515 | |
| -1 | -17,367,515 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 17,367,515.
Example:
1 x 17,367,515 = 17,367,515
and
-1 x -17,367,515 = 17,367,515
Notice both answers equal 17,367,515
With that explanation out of the way, let's continue. Next, we take the number 17,367,515 and divide it by 2:
17,367,515 ÷ 2 = 8,683,757.5
If the quotient is a whole number, then 2 and 8,683,757.5 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 | 17,367,515 | |
| -1 | -17,367,515 |
Now, we try dividing 17,367,515 by 3:
17,367,515 ÷ 3 = 5,789,171.6667
If the quotient is a whole number, then 3 and 5,789,171.6667 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 | 17,367,515 | |
| -1 | -17,367,515 |
Let's try dividing by 4:
17,367,515 ÷ 4 = 4,341,878.75
If the quotient is a whole number, then 4 and 4,341,878.75 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 | 17,367,515 | |
| -1 | 17,367,515 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 109 | 545 | 1,199 | 2,897 | 5,995 | 14,485 | 31,867 | 159,335 | 315,773 | 1,578,865 | 3,473,503 | 17,367,515 |
| -1 | -5 | -11 | -55 | -109 | -545 | -1,199 | -2,897 | -5,995 | -14,485 | -31,867 | -159,335 | -315,773 | -1,578,865 | -3,473,503 | -17,367,515 |
