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 1,834,217, 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 | 1,834,217 | |
| -1 | -1,834,217 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,834,217.
Example:
1 x 1,834,217 = 1,834,217
and
-1 x -1,834,217 = 1,834,217
Notice both answers equal 1,834,217
With that explanation out of the way, let's continue. Next, we take the number 1,834,217 and divide it by 2:
1,834,217 ÷ 2 = 917,108.5
If the quotient is a whole number, then 2 and 917,108.5 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 | 1,834,217 | |
| -1 | -1,834,217 |
Now, we try dividing 1,834,217 by 3:
1,834,217 ÷ 3 = 611,405.6667
If the quotient is a whole number, then 3 and 611,405.6667 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 | 1,834,217 | |
| -1 | -1,834,217 |
Let's try dividing by 4:
1,834,217 ÷ 4 = 458,554.25
If the quotient is a whole number, then 4 and 458,554.25 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 | 1,834,217 | |
| -1 | 1,834,217 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 41 | 49 | 77 | 83 | 287 | 451 | 539 | 581 | 913 | 2,009 | 3,157 | 3,403 | 4,067 | 6,391 | 22,099 | 23,821 | 37,433 | 44,737 | 166,747 | 262,031 | 1,834,217 |
| -1 | -7 | -11 | -41 | -49 | -77 | -83 | -287 | -451 | -539 | -581 | -913 | -2,009 | -3,157 | -3,403 | -4,067 | -6,391 | -22,099 | -23,821 | -37,433 | -44,737 | -166,747 | -262,031 | -1,834,217 |
