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 135,325,543, 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 | 135,325,543 | |
| -1 | -135,325,543 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 135,325,543.
Example:
1 x 135,325,543 = 135,325,543
and
-1 x -135,325,543 = 135,325,543
Notice both answers equal 135,325,543
With that explanation out of the way, let's continue. Next, we take the number 135,325,543 and divide it by 2:
135,325,543 ÷ 2 = 67,662,771.5
If the quotient is a whole number, then 2 and 67,662,771.5 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 | 135,325,543 | |
| -1 | -135,325,543 |
Now, we try dividing 135,325,543 by 3:
135,325,543 ÷ 3 = 45,108,514.3333
If the quotient is a whole number, then 3 and 45,108,514.3333 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 | 135,325,543 | |
| -1 | -135,325,543 |
Let's try dividing by 4:
135,325,543 ÷ 4 = 33,831,385.75
If the quotient is a whole number, then 4 and 33,831,385.75 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 | 135,325,543 | |
| -1 | 135,325,543 |
If you did it right, you will end up with this table:
| 1 | 19 | 41 | 223 | 361 | 779 | 1,681 | 4,237 | 9,143 | 14,801 | 31,939 | 80,503 | 173,717 | 374,863 | 606,841 | 3,300,623 | 7,122,397 | 135,325,543 |
| -1 | -19 | -41 | -223 | -361 | -779 | -1,681 | -4,237 | -9,143 | -14,801 | -31,939 | -80,503 | -173,717 | -374,863 | -606,841 | -3,300,623 | -7,122,397 | -135,325,543 |
