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 17,795,615, 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 | 17,795,615 | |
| -1 | -17,795,615 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 17,795,615.
Example:
1 x 17,795,615 = 17,795,615
and
-1 x -17,795,615 = 17,795,615
Notice both answers equal 17,795,615
With that explanation out of the way, let's continue. Next, we take the number 17,795,615 and divide it by 2:
17,795,615 ÷ 2 = 8,897,807.5
If the quotient is a whole number, then 2 and 8,897,807.5 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 | 17,795,615 | |
| -1 | -17,795,615 |
Now, we try dividing 17,795,615 by 3:
17,795,615 ÷ 3 = 5,931,871.6667
If the quotient is a whole number, then 3 and 5,931,871.6667 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 | 17,795,615 | |
| -1 | -17,795,615 |
Let's try dividing by 4:
17,795,615 ÷ 4 = 4,448,903.75
If the quotient is a whole number, then 4 and 4,448,903.75 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 | 17,795,615 | |
| -1 | 17,795,615 |
If you did it right, you will end up with this table:
| 1 | 5 | 83 | 137 | 313 | 415 | 685 | 1,565 | 11,371 | 25,979 | 42,881 | 56,855 | 129,895 | 214,405 | 3,559,123 | 17,795,615 |
| -1 | -5 | -83 | -137 | -313 | -415 | -685 | -1,565 | -11,371 | -25,979 | -42,881 | -56,855 | -129,895 | -214,405 | -3,559,123 | -17,795,615 |
