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 1,853,887, 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 | 1,853,887 | |
| -1 | -1,853,887 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,853,887.
Example:
1 x 1,853,887 = 1,853,887
and
-1 x -1,853,887 = 1,853,887
Notice both answers equal 1,853,887
With that explanation out of the way, let's continue. Next, we take the number 1,853,887 and divide it by 2:
1,853,887 ÷ 2 = 926,943.5
If the quotient is a whole number, then 2 and 926,943.5 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 | 1,853,887 | |
| -1 | -1,853,887 |
Now, we try dividing 1,853,887 by 3:
1,853,887 ÷ 3 = 617,962.3333
If the quotient is a whole number, then 3 and 617,962.3333 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 | 1,853,887 | |
| -1 | -1,853,887 |
Let's try dividing by 4:
1,853,887 ÷ 4 = 463,471.75
If the quotient is a whole number, then 4 and 463,471.75 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 | 1,853,887 | |
| -1 | 1,853,887 |
If you did it right, you will end up with this table:
| 1 | 7 | 19 | 53 | 133 | 263 | 371 | 1,007 | 1,841 | 4,997 | 7,049 | 13,939 | 34,979 | 97,573 | 264,841 | 1,853,887 |
| -1 | -7 | -19 | -53 | -133 | -263 | -371 | -1,007 | -1,841 | -4,997 | -7,049 | -13,939 | -34,979 | -97,573 | -264,841 | -1,853,887 |
