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 260,756,429, 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 | 260,756,429 | |
| -1 | -260,756,429 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 260,756,429.
Example:
1 x 260,756,429 = 260,756,429
and
-1 x -260,756,429 = 260,756,429
Notice both answers equal 260,756,429
With that explanation out of the way, let's continue. Next, we take the number 260,756,429 and divide it by 2:
260,756,429 ÷ 2 = 130,378,214.5
If the quotient is a whole number, then 2 and 130,378,214.5 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 | 260,756,429 | |
| -1 | -260,756,429 |
Now, we try dividing 260,756,429 by 3:
260,756,429 ÷ 3 = 86,918,809.6667
If the quotient is a whole number, then 3 and 86,918,809.6667 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 | 260,756,429 | |
| -1 | -260,756,429 |
Let's try dividing by 4:
260,756,429 ÷ 4 = 65,189,107.25
If the quotient is a whole number, then 4 and 65,189,107.25 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 | 260,756,429 | |
| -1 | 260,756,429 |
If you did it right, you will end up with this table:
| 1 | 29 | 43 | 67 | 1,247 | 1,943 | 2,881 | 3,121 | 83,549 | 90,509 | 134,203 | 209,107 | 3,891,887 | 6,064,103 | 8,991,601 | 260,756,429 |
| -1 | -29 | -43 | -67 | -1,247 | -1,943 | -2,881 | -3,121 | -83,549 | -90,509 | -134,203 | -209,107 | -3,891,887 | -6,064,103 | -8,991,601 | -260,756,429 |
