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 1,821,635, 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 | 1,821,635 | |
| -1 | -1,821,635 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,821,635.
Example:
1 x 1,821,635 = 1,821,635
and
-1 x -1,821,635 = 1,821,635
Notice both answers equal 1,821,635
With that explanation out of the way, let's continue. Next, we take the number 1,821,635 and divide it by 2:
1,821,635 ÷ 2 = 910,817.5
If the quotient is a whole number, then 2 and 910,817.5 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 | 1,821,635 | |
| -1 | -1,821,635 |
Now, we try dividing 1,821,635 by 3:
1,821,635 ÷ 3 = 607,211.6667
If the quotient is a whole number, then 3 and 607,211.6667 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 | 1,821,635 | |
| -1 | -1,821,635 |
Let's try dividing by 4:
1,821,635 ÷ 4 = 455,408.75
If the quotient is a whole number, then 4 and 455,408.75 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 | 1,821,635 | |
| -1 | 1,821,635 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 29 | 85 | 145 | 493 | 739 | 2,465 | 3,695 | 12,563 | 21,431 | 62,815 | 107,155 | 364,327 | 1,821,635 |
| -1 | -5 | -17 | -29 | -85 | -145 | -493 | -739 | -2,465 | -3,695 | -12,563 | -21,431 | -62,815 | -107,155 | -364,327 | -1,821,635 |
