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 4,068,635, 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 | 4,068,635 | |
| -1 | -4,068,635 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 4,068,635.
Example:
1 x 4,068,635 = 4,068,635
and
-1 x -4,068,635 = 4,068,635
Notice both answers equal 4,068,635
With that explanation out of the way, let's continue. Next, we take the number 4,068,635 and divide it by 2:
4,068,635 ÷ 2 = 2,034,317.5
If the quotient is a whole number, then 2 and 2,034,317.5 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 | 4,068,635 | |
| -1 | -4,068,635 |
Now, we try dividing 4,068,635 by 3:
4,068,635 ÷ 3 = 1,356,211.6667
If the quotient is a whole number, then 3 and 1,356,211.6667 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 | 4,068,635 | |
| -1 | -4,068,635 |
Let's try dividing by 4:
4,068,635 ÷ 4 = 1,017,158.75
If the quotient is a whole number, then 4 and 1,017,158.75 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 | 4,068,635 | |
| -1 | 4,068,635 |
If you did it right, you will end up with this table:
| 1 | 5 | 41 | 89 | 205 | 223 | 445 | 1,115 | 3,649 | 9,143 | 18,245 | 19,847 | 45,715 | 99,235 | 813,727 | 4,068,635 |
| -1 | -5 | -41 | -89 | -205 | -223 | -445 | -1,115 | -3,649 | -9,143 | -18,245 | -19,847 | -45,715 | -99,235 | -813,727 | -4,068,635 |
