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 260,526,167, 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 | 260,526,167 | |
| -1 | -260,526,167 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 260,526,167.
Example:
1 x 260,526,167 = 260,526,167
and
-1 x -260,526,167 = 260,526,167
Notice both answers equal 260,526,167
With that explanation out of the way, let's continue. Next, we take the number 260,526,167 and divide it by 2:
260,526,167 ÷ 2 = 130,263,083.5
If the quotient is a whole number, then 2 and 130,263,083.5 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 | 260,526,167 | |
| -1 | -260,526,167 |
Now, we try dividing 260,526,167 by 3:
260,526,167 ÷ 3 = 86,842,055.6667
If the quotient is a whole number, then 3 and 86,842,055.6667 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 | 260,526,167 | |
| -1 | -260,526,167 |
Let's try dividing by 4:
260,526,167 ÷ 4 = 65,131,541.75
If the quotient is a whole number, then 4 and 65,131,541.75 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 | 260,526,167 | |
| -1 | 260,526,167 |
If you did it right, you will end up with this table:
| 1 | 11 | 101 | 421 | 557 | 1,111 | 4,631 | 6,127 | 42,521 | 56,257 | 234,497 | 467,731 | 618,827 | 2,579,467 | 23,684,197 | 260,526,167 |
| -1 | -11 | -101 | -421 | -557 | -1,111 | -4,631 | -6,127 | -42,521 | -56,257 | -234,497 | -467,731 | -618,827 | -2,579,467 | -23,684,197 | -260,526,167 |
