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 260,202,455, 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 | 260,202,455 | |
| -1 | -260,202,455 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 260,202,455.
Example:
1 x 260,202,455 = 260,202,455
and
-1 x -260,202,455 = 260,202,455
Notice both answers equal 260,202,455
With that explanation out of the way, let's continue. Next, we take the number 260,202,455 and divide it by 2:
260,202,455 ÷ 2 = 130,101,227.5
If the quotient is a whole number, then 2 and 130,101,227.5 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 | 260,202,455 | |
| -1 | -260,202,455 |
Now, we try dividing 260,202,455 by 3:
260,202,455 ÷ 3 = 86,734,151.6667
If the quotient is a whole number, then 3 and 86,734,151.6667 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 | 260,202,455 | |
| -1 | -260,202,455 |
Let's try dividing by 4:
260,202,455 ÷ 4 = 65,050,613.75
If the quotient is a whole number, then 4 and 65,050,613.75 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 | 260,202,455 | |
| -1 | 260,202,455 |
If you did it right, you will end up with this table:
| 1 | 5 | 179 | 307 | 895 | 947 | 1,535 | 4,735 | 54,953 | 169,513 | 274,765 | 290,729 | 847,565 | 1,453,645 | 52,040,491 | 260,202,455 |
| -1 | -5 | -179 | -307 | -895 | -947 | -1,535 | -4,735 | -54,953 | -169,513 | -274,765 | -290,729 | -847,565 | -1,453,645 | -52,040,491 | -260,202,455 |
