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 260,413,361, 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 | 260,413,361 | |
| -1 | -260,413,361 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 260,413,361.
Example:
1 x 260,413,361 = 260,413,361
and
-1 x -260,413,361 = 260,413,361
Notice both answers equal 260,413,361
With that explanation out of the way, let's continue. Next, we take the number 260,413,361 and divide it by 2:
260,413,361 ÷ 2 = 130,206,680.5
If the quotient is a whole number, then 2 and 130,206,680.5 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 | 260,413,361 | |
| -1 | -260,413,361 |
Now, we try dividing 260,413,361 by 3:
260,413,361 ÷ 3 = 86,804,453.6667
If the quotient is a whole number, then 3 and 86,804,453.6667 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 | 260,413,361 | |
| -1 | -260,413,361 |
Let's try dividing by 4:
260,413,361 ÷ 4 = 65,103,340.25
If the quotient is a whole number, then 4 and 65,103,340.25 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 | 260,413,361 | |
| -1 | 260,413,361 |
If you did it right, you will end up with this table:
| 1 | 13 | 17 | 31 | 221 | 403 | 527 | 6,851 | 38,011 | 494,143 | 646,187 | 1,178,341 | 8,400,431 | 15,318,433 | 20,031,797 | 260,413,361 |
| -1 | -13 | -17 | -31 | -221 | -403 | -527 | -6,851 | -38,011 | -494,143 | -646,187 | -1,178,341 | -8,400,431 | -15,318,433 | -20,031,797 | -260,413,361 |
