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 260,026,115, 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 | 260,026,115 | |
| -1 | -260,026,115 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 260,026,115.
Example:
1 x 260,026,115 = 260,026,115
and
-1 x -260,026,115 = 260,026,115
Notice both answers equal 260,026,115
With that explanation out of the way, let's continue. Next, we take the number 260,026,115 and divide it by 2:
260,026,115 ÷ 2 = 130,013,057.5
If the quotient is a whole number, then 2 and 130,013,057.5 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 | 260,026,115 | |
| -1 | -260,026,115 |
Now, we try dividing 260,026,115 by 3:
260,026,115 ÷ 3 = 86,675,371.6667
If the quotient is a whole number, then 3 and 86,675,371.6667 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 | 260,026,115 | |
| -1 | -260,026,115 |
Let's try dividing by 4:
260,026,115 ÷ 4 = 65,006,528.75
If the quotient is a whole number, then 4 and 65,006,528.75 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 | 260,026,115 | |
| -1 | 260,026,115 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 95 | 877 | 3,121 | 4,385 | 15,605 | 16,663 | 59,299 | 83,315 | 296,495 | 2,737,117 | 13,685,585 | 52,005,223 | 260,026,115 |
| -1 | -5 | -19 | -95 | -877 | -3,121 | -4,385 | -15,605 | -16,663 | -59,299 | -83,315 | -296,495 | -2,737,117 | -13,685,585 | -52,005,223 | -260,026,115 |
