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 150,804,815, 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 | 150,804,815 | |
| -1 | -150,804,815 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 150,804,815.
Example:
1 x 150,804,815 = 150,804,815
and
-1 x -150,804,815 = 150,804,815
Notice both answers equal 150,804,815
With that explanation out of the way, let's continue. Next, we take the number 150,804,815 and divide it by 2:
150,804,815 ÷ 2 = 75,402,407.5
If the quotient is a whole number, then 2 and 75,402,407.5 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 | 150,804,815 | |
| -1 | -150,804,815 |
Now, we try dividing 150,804,815 by 3:
150,804,815 ÷ 3 = 50,268,271.6667
If the quotient is a whole number, then 3 and 50,268,271.6667 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 | 150,804,815 | |
| -1 | -150,804,815 |
Let's try dividing by 4:
150,804,815 ÷ 4 = 37,701,203.75
If the quotient is a whole number, then 4 and 37,701,203.75 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 | 150,804,815 | |
| -1 | 150,804,815 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 179 | 895 | 1,253 | 6,265 | 24,071 | 120,355 | 168,497 | 842,485 | 4,308,709 | 21,543,545 | 30,160,963 | 150,804,815 |
| -1 | -5 | -7 | -35 | -179 | -895 | -1,253 | -6,265 | -24,071 | -120,355 | -168,497 | -842,485 | -4,308,709 | -21,543,545 | -30,160,963 | -150,804,815 |
