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 1,508,375, 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 | 1,508,375 | |
| -1 | -1,508,375 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,508,375.
Example:
1 x 1,508,375 = 1,508,375
and
-1 x -1,508,375 = 1,508,375
Notice both answers equal 1,508,375
With that explanation out of the way, let's continue. Next, we take the number 1,508,375 and divide it by 2:
1,508,375 ÷ 2 = 754,187.5
If the quotient is a whole number, then 2 and 754,187.5 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 | 1,508,375 | |
| -1 | -1,508,375 |
Now, we try dividing 1,508,375 by 3:
1,508,375 ÷ 3 = 502,791.6667
If the quotient is a whole number, then 3 and 502,791.6667 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 | 1,508,375 | |
| -1 | -1,508,375 |
Let's try dividing by 4:
1,508,375 ÷ 4 = 377,093.75
If the quotient is a whole number, then 4 and 377,093.75 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 | 1,508,375 | |
| -1 | 1,508,375 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 25 | 55 | 125 | 275 | 1,097 | 1,375 | 5,485 | 12,067 | 27,425 | 60,335 | 137,125 | 301,675 | 1,508,375 |
| -1 | -5 | -11 | -25 | -55 | -125 | -275 | -1,097 | -1,375 | -5,485 | -12,067 | -27,425 | -60,335 | -137,125 | -301,675 | -1,508,375 |
