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 260,148,317, 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 | 260,148,317 | |
| -1 | -260,148,317 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 260,148,317.
Example:
1 x 260,148,317 = 260,148,317
and
-1 x -260,148,317 = 260,148,317
Notice both answers equal 260,148,317
With that explanation out of the way, let's continue. Next, we take the number 260,148,317 and divide it by 2:
260,148,317 ÷ 2 = 130,074,158.5
If the quotient is a whole number, then 2 and 130,074,158.5 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 | 260,148,317 | |
| -1 | -260,148,317 |
Now, we try dividing 260,148,317 by 3:
260,148,317 ÷ 3 = 86,716,105.6667
If the quotient is a whole number, then 3 and 86,716,105.6667 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 | 260,148,317 | |
| -1 | -260,148,317 |
Let's try dividing by 4:
260,148,317 ÷ 4 = 65,037,079.25
If the quotient is a whole number, then 4 and 65,037,079.25 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 | 260,148,317 | |
| -1 | 260,148,317 |
If you did it right, you will end up with this table:
| 1 | 11 | 13 | 143 | 367 | 4,037 | 4,771 | 4,957 | 52,481 | 54,527 | 64,441 | 708,851 | 1,819,219 | 20,011,409 | 23,649,847 | 260,148,317 |
| -1 | -11 | -13 | -143 | -367 | -4,037 | -4,771 | -4,957 | -52,481 | -54,527 | -64,441 | -708,851 | -1,819,219 | -20,011,409 | -23,649,847 | -260,148,317 |
