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 4,066,285, 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 | 4,066,285 | |
| -1 | -4,066,285 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 4,066,285.
Example:
1 x 4,066,285 = 4,066,285
and
-1 x -4,066,285 = 4,066,285
Notice both answers equal 4,066,285
With that explanation out of the way, let's continue. Next, we take the number 4,066,285 and divide it by 2:
4,066,285 ÷ 2 = 2,033,142.5
If the quotient is a whole number, then 2 and 2,033,142.5 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 | 4,066,285 | |
| -1 | -4,066,285 |
Now, we try dividing 4,066,285 by 3:
4,066,285 ÷ 3 = 1,355,428.3333
If the quotient is a whole number, then 3 and 1,355,428.3333 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 | 4,066,285 | |
| -1 | -4,066,285 |
Let's try dividing by 4:
4,066,285 ÷ 4 = 1,016,571.25
If the quotient is a whole number, then 4 and 1,016,571.25 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 | 4,066,285 | |
| -1 | 4,066,285 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 23 | 95 | 115 | 437 | 1,861 | 2,185 | 9,305 | 35,359 | 42,803 | 176,795 | 214,015 | 813,257 | 4,066,285 |
| -1 | -5 | -19 | -23 | -95 | -115 | -437 | -1,861 | -2,185 | -9,305 | -35,359 | -42,803 | -176,795 | -214,015 | -813,257 | -4,066,285 |
