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 1,831,315, 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 | 1,831,315 | |
| -1 | -1,831,315 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,831,315.
Example:
1 x 1,831,315 = 1,831,315
and
-1 x -1,831,315 = 1,831,315
Notice both answers equal 1,831,315
With that explanation out of the way, let's continue. Next, we take the number 1,831,315 and divide it by 2:
1,831,315 ÷ 2 = 915,657.5
If the quotient is a whole number, then 2 and 915,657.5 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 | 1,831,315 | |
| -1 | -1,831,315 |
Now, we try dividing 1,831,315 by 3:
1,831,315 ÷ 3 = 610,438.3333
If the quotient is a whole number, then 3 and 610,438.3333 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 | 1,831,315 | |
| -1 | -1,831,315 |
Let's try dividing by 4:
1,831,315 ÷ 4 = 457,828.75
If the quotient is a whole number, then 4 and 457,828.75 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 | 1,831,315 | |
| -1 | 1,831,315 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 37 | 95 | 185 | 521 | 703 | 2,605 | 3,515 | 9,899 | 19,277 | 49,495 | 96,385 | 366,263 | 1,831,315 |
| -1 | -5 | -19 | -37 | -95 | -185 | -521 | -703 | -2,605 | -3,515 | -9,899 | -19,277 | -49,495 | -96,385 | -366,263 | -1,831,315 |
