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 263,662,715, 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 | 263,662,715 | |
| -1 | -263,662,715 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 263,662,715.
Example:
1 x 263,662,715 = 263,662,715
and
-1 x -263,662,715 = 263,662,715
Notice both answers equal 263,662,715
With that explanation out of the way, let's continue. Next, we take the number 263,662,715 and divide it by 2:
263,662,715 ÷ 2 = 131,831,357.5
If the quotient is a whole number, then 2 and 131,831,357.5 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 | 263,662,715 | |
| -1 | -263,662,715 |
Now, we try dividing 263,662,715 by 3:
263,662,715 ÷ 3 = 87,887,571.6667
If the quotient is a whole number, then 3 and 87,887,571.6667 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 | 263,662,715 | |
| -1 | -263,662,715 |
Let's try dividing by 4:
263,662,715 ÷ 4 = 65,915,678.75
If the quotient is a whole number, then 4 and 65,915,678.75 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 | 263,662,715 | |
| -1 | 263,662,715 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 47 | 95 | 235 | 893 | 4,465 | 59,051 | 295,255 | 1,121,969 | 2,775,397 | 5,609,845 | 13,876,985 | 52,732,543 | 263,662,715 |
| -1 | -5 | -19 | -47 | -95 | -235 | -893 | -4,465 | -59,051 | -295,255 | -1,121,969 | -2,775,397 | -5,609,845 | -13,876,985 | -52,732,543 | -263,662,715 |
