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 260,202,523, 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 | 260,202,523 | |
| -1 | -260,202,523 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 260,202,523.
Example:
1 x 260,202,523 = 260,202,523
and
-1 x -260,202,523 = 260,202,523
Notice both answers equal 260,202,523
With that explanation out of the way, let's continue. Next, we take the number 260,202,523 and divide it by 2:
260,202,523 ÷ 2 = 130,101,261.5
If the quotient is a whole number, then 2 and 130,101,261.5 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 | 260,202,523 | |
| -1 | -260,202,523 |
Now, we try dividing 260,202,523 by 3:
260,202,523 ÷ 3 = 86,734,174.3333
If the quotient is a whole number, then 3 and 86,734,174.3333 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 | 260,202,523 | |
| -1 | -260,202,523 |
Let's try dividing by 4:
260,202,523 ÷ 4 = 65,050,630.75
If the quotient is a whole number, then 4 and 65,050,630.75 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 | 260,202,523 | |
| -1 | 260,202,523 |
If you did it right, you will end up with this table:
| 1 | 7 | 41 | 181 | 287 | 1,267 | 5,009 | 7,421 | 35,063 | 51,947 | 205,369 | 906,629 | 1,437,583 | 6,346,403 | 37,171,789 | 260,202,523 |
| -1 | -7 | -41 | -181 | -287 | -1,267 | -5,009 | -7,421 | -35,063 | -51,947 | -205,369 | -906,629 | -1,437,583 | -6,346,403 | -37,171,789 | -260,202,523 |
