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 135,325,571, 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 | 135,325,571 | |
| -1 | -135,325,571 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 135,325,571.
Example:
1 x 135,325,571 = 135,325,571
and
-1 x -135,325,571 = 135,325,571
Notice both answers equal 135,325,571
With that explanation out of the way, let's continue. Next, we take the number 135,325,571 and divide it by 2:
135,325,571 ÷ 2 = 67,662,785.5
If the quotient is a whole number, then 2 and 67,662,785.5 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 | 135,325,571 | |
| -1 | -135,325,571 |
Now, we try dividing 135,325,571 by 3:
135,325,571 ÷ 3 = 45,108,523.6667
If the quotient is a whole number, then 3 and 45,108,523.6667 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 | 135,325,571 | |
| -1 | -135,325,571 |
Let's try dividing by 4:
135,325,571 ÷ 4 = 33,831,392.75
If the quotient is a whole number, then 4 and 33,831,392.75 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 | 135,325,571 | |
| -1 | 135,325,571 |
If you did it right, you will end up with this table:
| 1 | 29 | 31 | 109 | 899 | 1,381 | 3,161 | 3,379 | 40,049 | 42,811 | 97,991 | 150,529 | 1,241,519 | 4,365,341 | 4,666,399 | 135,325,571 |
| -1 | -29 | -31 | -109 | -899 | -1,381 | -3,161 | -3,379 | -40,049 | -42,811 | -97,991 | -150,529 | -1,241,519 | -4,365,341 | -4,666,399 | -135,325,571 |
