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 260,523,497, 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 | 260,523,497 | |
| -1 | -260,523,497 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 260,523,497.
Example:
1 x 260,523,497 = 260,523,497
and
-1 x -260,523,497 = 260,523,497
Notice both answers equal 260,523,497
With that explanation out of the way, let's continue. Next, we take the number 260,523,497 and divide it by 2:
260,523,497 ÷ 2 = 130,261,748.5
If the quotient is a whole number, then 2 and 130,261,748.5 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 | 260,523,497 | |
| -1 | -260,523,497 |
Now, we try dividing 260,523,497 by 3:
260,523,497 ÷ 3 = 86,841,165.6667
If the quotient is a whole number, then 3 and 86,841,165.6667 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 | 260,523,497 | |
| -1 | -260,523,497 |
Let's try dividing by 4:
260,523,497 ÷ 4 = 65,130,874.25
If the quotient is a whole number, then 4 and 65,130,874.25 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 | 260,523,497 | |
| -1 | 260,523,497 |
If you did it right, you will end up with this table:
| 1 | 13 | 19 | 61 | 247 | 793 | 1,159 | 15,067 | 17,291 | 224,783 | 328,529 | 1,054,751 | 4,270,877 | 13,711,763 | 20,040,269 | 260,523,497 |
| -1 | -13 | -19 | -61 | -247 | -793 | -1,159 | -15,067 | -17,291 | -224,783 | -328,529 | -1,054,751 | -4,270,877 | -13,711,763 | -20,040,269 | -260,523,497 |
