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 17,896,495, 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 | 17,896,495 | |
| -1 | -17,896,495 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 17,896,495.
Example:
1 x 17,896,495 = 17,896,495
and
-1 x -17,896,495 = 17,896,495
Notice both answers equal 17,896,495
With that explanation out of the way, let's continue. Next, we take the number 17,896,495 and divide it by 2:
17,896,495 ÷ 2 = 8,948,247.5
If the quotient is a whole number, then 2 and 8,948,247.5 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 | 17,896,495 | |
| -1 | -17,896,495 |
Now, we try dividing 17,896,495 by 3:
17,896,495 ÷ 3 = 5,965,498.3333
If the quotient is a whole number, then 3 and 5,965,498.3333 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 | 17,896,495 | |
| -1 | -17,896,495 |
Let's try dividing by 4:
17,896,495 ÷ 4 = 4,474,123.75
If the quotient is a whole number, then 4 and 4,474,123.75 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 | 17,896,495 | |
| -1 | 17,896,495 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 85 | 311 | 677 | 1,555 | 3,385 | 5,287 | 11,509 | 26,435 | 57,545 | 210,547 | 1,052,735 | 3,579,299 | 17,896,495 |
| -1 | -5 | -17 | -85 | -311 | -677 | -1,555 | -3,385 | -5,287 | -11,509 | -26,435 | -57,545 | -210,547 | -1,052,735 | -3,579,299 | -17,896,495 |
