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 17,411,615, 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 | 17,411,615 | |
| -1 | -17,411,615 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 17,411,615.
Example:
1 x 17,411,615 = 17,411,615
and
-1 x -17,411,615 = 17,411,615
Notice both answers equal 17,411,615
With that explanation out of the way, let's continue. Next, we take the number 17,411,615 and divide it by 2:
17,411,615 ÷ 2 = 8,705,807.5
If the quotient is a whole number, then 2 and 8,705,807.5 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 | 17,411,615 | |
| -1 | -17,411,615 |
Now, we try dividing 17,411,615 by 3:
17,411,615 ÷ 3 = 5,803,871.6667
If the quotient is a whole number, then 3 and 5,803,871.6667 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 | 17,411,615 | |
| -1 | -17,411,615 |
Let's try dividing by 4:
17,411,615 ÷ 4 = 4,352,903.75
If the quotient is a whole number, then 4 and 4,352,903.75 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 | 17,411,615 | |
| -1 | 17,411,615 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 31 | 65 | 155 | 403 | 2,015 | 8,641 | 43,205 | 112,333 | 267,871 | 561,665 | 1,339,355 | 3,482,323 | 17,411,615 |
| -1 | -5 | -13 | -31 | -65 | -155 | -403 | -2,015 | -8,641 | -43,205 | -112,333 | -267,871 | -561,665 | -1,339,355 | -3,482,323 | -17,411,615 |
