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 1,533,665, 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 | 1,533,665 | |
| -1 | -1,533,665 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,533,665.
Example:
1 x 1,533,665 = 1,533,665
and
-1 x -1,533,665 = 1,533,665
Notice both answers equal 1,533,665
With that explanation out of the way, let's continue. Next, we take the number 1,533,665 and divide it by 2:
1,533,665 ÷ 2 = 766,832.5
If the quotient is a whole number, then 2 and 766,832.5 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 | 1,533,665 | |
| -1 | -1,533,665 |
Now, we try dividing 1,533,665 by 3:
1,533,665 ÷ 3 = 511,221.6667
If the quotient is a whole number, then 3 and 511,221.6667 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 | 1,533,665 | |
| -1 | -1,533,665 |
Let's try dividing by 4:
1,533,665 ÷ 4 = 383,416.25
If the quotient is a whole number, then 4 and 383,416.25 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 | 1,533,665 | |
| -1 | 1,533,665 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 29 | 35 | 145 | 203 | 1,015 | 1,511 | 7,555 | 10,577 | 43,819 | 52,885 | 219,095 | 306,733 | 1,533,665 |
| -1 | -5 | -7 | -29 | -35 | -145 | -203 | -1,015 | -1,511 | -7,555 | -10,577 | -43,819 | -52,885 | -219,095 | -306,733 | -1,533,665 |
