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 260,104,165, 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 | 260,104,165 | |
| -1 | -260,104,165 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 260,104,165.
Example:
1 x 260,104,165 = 260,104,165
and
-1 x -260,104,165 = 260,104,165
Notice both answers equal 260,104,165
With that explanation out of the way, let's continue. Next, we take the number 260,104,165 and divide it by 2:
260,104,165 ÷ 2 = 130,052,082.5
If the quotient is a whole number, then 2 and 130,052,082.5 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 | 260,104,165 | |
| -1 | -260,104,165 |
Now, we try dividing 260,104,165 by 3:
260,104,165 ÷ 3 = 86,701,388.3333
If the quotient is a whole number, then 3 and 86,701,388.3333 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 | 260,104,165 | |
| -1 | -260,104,165 |
Let's try dividing by 4:
260,104,165 ÷ 4 = 65,026,041.25
If the quotient is a whole number, then 4 and 65,026,041.25 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 | 260,104,165 | |
| -1 | 260,104,165 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 85 | 911 | 3,359 | 4,555 | 15,487 | 16,795 | 57,103 | 77,435 | 285,515 | 3,060,049 | 15,300,245 | 52,020,833 | 260,104,165 |
| -1 | -5 | -17 | -85 | -911 | -3,359 | -4,555 | -15,487 | -16,795 | -57,103 | -77,435 | -285,515 | -3,060,049 | -15,300,245 | -52,020,833 | -260,104,165 |
