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 1,853,357, 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 | 1,853,357 | |
| -1 | -1,853,357 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,853,357.
Example:
1 x 1,853,357 = 1,853,357
and
-1 x -1,853,357 = 1,853,357
Notice both answers equal 1,853,357
With that explanation out of the way, let's continue. Next, we take the number 1,853,357 and divide it by 2:
1,853,357 ÷ 2 = 926,678.5
If the quotient is a whole number, then 2 and 926,678.5 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 | 1,853,357 | |
| -1 | -1,853,357 |
Now, we try dividing 1,853,357 by 3:
1,853,357 ÷ 3 = 617,785.6667
If the quotient is a whole number, then 3 and 617,785.6667 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 | 1,853,357 | |
| -1 | -1,853,357 |
Let's try dividing by 4:
1,853,357 ÷ 4 = 463,339.25
If the quotient is a whole number, then 4 and 463,339.25 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 | 1,853,357 | |
| -1 | 1,853,357 |
If you did it right, you will end up with this table:
| 1 | 11 | 17 | 53 | 121 | 187 | 289 | 583 | 901 | 2,057 | 3,179 | 6,413 | 9,911 | 15,317 | 34,969 | 109,021 | 168,487 | 1,853,357 |
| -1 | -11 | -17 | -53 | -121 | -187 | -289 | -583 | -901 | -2,057 | -3,179 | -6,413 | -9,911 | -15,317 | -34,969 | -109,021 | -168,487 | -1,853,357 |
