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 260,401,349, 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 | 260,401,349 | |
| -1 | -260,401,349 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 260,401,349.
Example:
1 x 260,401,349 = 260,401,349
and
-1 x -260,401,349 = 260,401,349
Notice both answers equal 260,401,349
With that explanation out of the way, let's continue. Next, we take the number 260,401,349 and divide it by 2:
260,401,349 ÷ 2 = 130,200,674.5
If the quotient is a whole number, then 2 and 130,200,674.5 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 | 260,401,349 | |
| -1 | -260,401,349 |
Now, we try dividing 260,401,349 by 3:
260,401,349 ÷ 3 = 86,800,449.6667
If the quotient is a whole number, then 3 and 86,800,449.6667 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 | 260,401,349 | |
| -1 | -260,401,349 |
Let's try dividing by 4:
260,401,349 ÷ 4 = 65,100,337.25
If the quotient is a whole number, then 4 and 65,100,337.25 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 | 260,401,349 | |
| -1 | 260,401,349 |
If you did it right, you will end up with this table:
| 1 | 13 | 53 | 139 | 689 | 1,807 | 2,719 | 7,367 | 35,347 | 95,771 | 144,107 | 377,941 | 1,873,391 | 4,913,233 | 20,030,873 | 260,401,349 |
| -1 | -13 | -53 | -139 | -689 | -1,807 | -2,719 | -7,367 | -35,347 | -95,771 | -144,107 | -377,941 | -1,873,391 | -4,913,233 | -20,030,873 | -260,401,349 |
