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 136,543,663, 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 | 136,543,663 | |
| -1 | -136,543,663 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 136,543,663.
Example:
1 x 136,543,663 = 136,543,663
and
-1 x -136,543,663 = 136,543,663
Notice both answers equal 136,543,663
With that explanation out of the way, let's continue. Next, we take the number 136,543,663 and divide it by 2:
136,543,663 ÷ 2 = 68,271,831.5
If the quotient is a whole number, then 2 and 68,271,831.5 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 | 136,543,663 | |
| -1 | -136,543,663 |
Now, we try dividing 136,543,663 by 3:
136,543,663 ÷ 3 = 45,514,554.3333
If the quotient is a whole number, then 3 and 45,514,554.3333 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 | 136,543,663 | |
| -1 | -136,543,663 |
Let's try dividing by 4:
136,543,663 ÷ 4 = 34,135,915.75
If the quotient is a whole number, then 4 and 34,135,915.75 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 | 136,543,663 | |
| -1 | 136,543,663 |
If you did it right, you will end up with this table:
| 1 | 23 | 107 | 113 | 491 | 2,461 | 2,599 | 11,293 | 12,091 | 52,537 | 55,483 | 278,093 | 1,208,351 | 1,276,109 | 5,936,681 | 136,543,663 |
| -1 | -23 | -107 | -113 | -491 | -2,461 | -2,599 | -11,293 | -12,091 | -52,537 | -55,483 | -278,093 | -1,208,351 | -1,276,109 | -5,936,681 | -136,543,663 |
