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 150,241,135, 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 | 150,241,135 | |
| -1 | -150,241,135 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 150,241,135.
Example:
1 x 150,241,135 = 150,241,135
and
-1 x -150,241,135 = 150,241,135
Notice both answers equal 150,241,135
With that explanation out of the way, let's continue. Next, we take the number 150,241,135 and divide it by 2:
150,241,135 ÷ 2 = 75,120,567.5
If the quotient is a whole number, then 2 and 75,120,567.5 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 | 150,241,135 | |
| -1 | -150,241,135 |
Now, we try dividing 150,241,135 by 3:
150,241,135 ÷ 3 = 50,080,378.3333
If the quotient is a whole number, then 3 and 50,080,378.3333 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 | 150,241,135 | |
| -1 | -150,241,135 |
Let's try dividing by 4:
150,241,135 ÷ 4 = 37,560,283.75
If the quotient is a whole number, then 4 and 37,560,283.75 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 | 150,241,135 | |
| -1 | 150,241,135 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 67 | 335 | 737 | 3,685 | 40,771 | 203,855 | 448,481 | 2,242,405 | 2,731,657 | 13,658,285 | 30,048,227 | 150,241,135 |
| -1 | -5 | -11 | -55 | -67 | -335 | -737 | -3,685 | -40,771 | -203,855 | -448,481 | -2,242,405 | -2,731,657 | -13,658,285 | -30,048,227 | -150,241,135 |
