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 260,466,775, 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 | 260,466,775 | |
| -1 | -260,466,775 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 260,466,775.
Example:
1 x 260,466,775 = 260,466,775
and
-1 x -260,466,775 = 260,466,775
Notice both answers equal 260,466,775
With that explanation out of the way, let's continue. Next, we take the number 260,466,775 and divide it by 2:
260,466,775 ÷ 2 = 130,233,387.5
If the quotient is a whole number, then 2 and 130,233,387.5 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 | 260,466,775 | |
| -1 | -260,466,775 |
Now, we try dividing 260,466,775 by 3:
260,466,775 ÷ 3 = 86,822,258.3333
If the quotient is a whole number, then 3 and 86,822,258.3333 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 | 260,466,775 | |
| -1 | -260,466,775 |
Let's try dividing by 4:
260,466,775 ÷ 4 = 65,116,693.75
If the quotient is a whole number, then 4 and 65,116,693.75 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 | 260,466,775 | |
| -1 | 260,466,775 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 25 | 85 | 241 | 425 | 1,205 | 2,543 | 4,097 | 6,025 | 12,715 | 20,485 | 43,231 | 63,575 | 102,425 | 216,155 | 612,863 | 1,080,775 | 3,064,315 | 10,418,671 | 15,321,575 | 52,093,355 | 260,466,775 |
| -1 | -5 | -17 | -25 | -85 | -241 | -425 | -1,205 | -2,543 | -4,097 | -6,025 | -12,715 | -20,485 | -43,231 | -63,575 | -102,425 | -216,155 | -612,863 | -1,080,775 | -3,064,315 | -10,418,671 | -15,321,575 | -52,093,355 | -260,466,775 |
