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 1,885,715, 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 | 1,885,715 | |
| -1 | -1,885,715 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,885,715.
Example:
1 x 1,885,715 = 1,885,715
and
-1 x -1,885,715 = 1,885,715
Notice both answers equal 1,885,715
With that explanation out of the way, let's continue. Next, we take the number 1,885,715 and divide it by 2:
1,885,715 ÷ 2 = 942,857.5
If the quotient is a whole number, then 2 and 942,857.5 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 | 1,885,715 | |
| -1 | -1,885,715 |
Now, we try dividing 1,885,715 by 3:
1,885,715 ÷ 3 = 628,571.6667
If the quotient is a whole number, then 3 and 628,571.6667 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 | 1,885,715 | |
| -1 | -1,885,715 |
Let's try dividing by 4:
1,885,715 ÷ 4 = 471,428.75
If the quotient is a whole number, then 4 and 471,428.75 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 | 1,885,715 | |
| -1 | 1,885,715 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 65 | 67 | 335 | 433 | 871 | 2,165 | 4,355 | 5,629 | 28,145 | 29,011 | 145,055 | 377,143 | 1,885,715 |
| -1 | -5 | -13 | -65 | -67 | -335 | -433 | -871 | -2,165 | -4,355 | -5,629 | -28,145 | -29,011 | -145,055 | -377,143 | -1,885,715 |
