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 260,771,075, 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 | 260,771,075 | |
| -1 | -260,771,075 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 260,771,075.
Example:
1 x 260,771,075 = 260,771,075
and
-1 x -260,771,075 = 260,771,075
Notice both answers equal 260,771,075
With that explanation out of the way, let's continue. Next, we take the number 260,771,075 and divide it by 2:
260,771,075 ÷ 2 = 130,385,537.5
If the quotient is a whole number, then 2 and 130,385,537.5 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 | 260,771,075 | |
| -1 | -260,771,075 |
Now, we try dividing 260,771,075 by 3:
260,771,075 ÷ 3 = 86,923,691.6667
If the quotient is a whole number, then 3 and 86,923,691.6667 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 | 260,771,075 | |
| -1 | -260,771,075 |
Let's try dividing by 4:
260,771,075 ÷ 4 = 65,192,768.75
If the quotient is a whole number, then 4 and 65,192,768.75 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 | 260,771,075 | |
| -1 | 260,771,075 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 25 | 85 | 263 | 425 | 1,315 | 2,333 | 4,471 | 6,575 | 11,665 | 22,355 | 39,661 | 58,325 | 111,775 | 198,305 | 613,579 | 991,525 | 3,067,895 | 10,430,843 | 15,339,475 | 52,154,215 | 260,771,075 |
| -1 | -5 | -17 | -25 | -85 | -263 | -425 | -1,315 | -2,333 | -4,471 | -6,575 | -11,665 | -22,355 | -39,661 | -58,325 | -111,775 | -198,305 | -613,579 | -991,525 | -3,067,895 | -10,430,843 | -15,339,475 | -52,154,215 | -260,771,075 |
