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 135,512,455, 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 | 135,512,455 | |
| -1 | -135,512,455 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 135,512,455.
Example:
1 x 135,512,455 = 135,512,455
and
-1 x -135,512,455 = 135,512,455
Notice both answers equal 135,512,455
With that explanation out of the way, let's continue. Next, we take the number 135,512,455 and divide it by 2:
135,512,455 ÷ 2 = 67,756,227.5
If the quotient is a whole number, then 2 and 67,756,227.5 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 | 135,512,455 | |
| -1 | -135,512,455 |
Now, we try dividing 135,512,455 by 3:
135,512,455 ÷ 3 = 45,170,818.3333
If the quotient is a whole number, then 3 and 45,170,818.3333 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 | 135,512,455 | |
| -1 | -135,512,455 |
Let's try dividing by 4:
135,512,455 ÷ 4 = 33,878,113.75
If the quotient is a whole number, then 4 and 33,878,113.75 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 | 135,512,455 | |
| -1 | 135,512,455 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 65 | 73 | 365 | 949 | 4,745 | 28,559 | 142,795 | 371,267 | 1,856,335 | 2,084,807 | 10,424,035 | 27,102,491 | 135,512,455 |
| -1 | -5 | -13 | -65 | -73 | -365 | -949 | -4,745 | -28,559 | -142,795 | -371,267 | -1,856,335 | -2,084,807 | -10,424,035 | -27,102,491 | -135,512,455 |
