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 1,605,635, 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 | 1,605,635 | |
| -1 | -1,605,635 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,605,635.
Example:
1 x 1,605,635 = 1,605,635
and
-1 x -1,605,635 = 1,605,635
Notice both answers equal 1,605,635
With that explanation out of the way, let's continue. Next, we take the number 1,605,635 and divide it by 2:
1,605,635 ÷ 2 = 802,817.5
If the quotient is a whole number, then 2 and 802,817.5 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 | 1,605,635 | |
| -1 | -1,605,635 |
Now, we try dividing 1,605,635 by 3:
1,605,635 ÷ 3 = 535,211.6667
If the quotient is a whole number, then 3 and 535,211.6667 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 | 1,605,635 | |
| -1 | -1,605,635 |
Let's try dividing by 4:
1,605,635 ÷ 4 = 401,408.75
If the quotient is a whole number, then 4 and 401,408.75 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 | 1,605,635 | |
| -1 | 1,605,635 |
If you did it right, you will end up with this table:
| 1 | 5 | 53 | 73 | 83 | 265 | 365 | 415 | 3,869 | 4,399 | 6,059 | 19,345 | 21,995 | 30,295 | 321,127 | 1,605,635 |
| -1 | -5 | -53 | -73 | -83 | -265 | -365 | -415 | -3,869 | -4,399 | -6,059 | -19,345 | -21,995 | -30,295 | -321,127 | -1,605,635 |
