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 4,004,755, 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 | 4,004,755 | |
| -1 | -4,004,755 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 4,004,755.
Example:
1 x 4,004,755 = 4,004,755
and
-1 x -4,004,755 = 4,004,755
Notice both answers equal 4,004,755
With that explanation out of the way, let's continue. Next, we take the number 4,004,755 and divide it by 2:
4,004,755 ÷ 2 = 2,002,377.5
If the quotient is a whole number, then 2 and 2,002,377.5 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 | 4,004,755 | |
| -1 | -4,004,755 |
Now, we try dividing 4,004,755 by 3:
4,004,755 ÷ 3 = 1,334,918.3333
If the quotient is a whole number, then 3 and 1,334,918.3333 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 | 4,004,755 | |
| -1 | -4,004,755 |
Let's try dividing by 4:
4,004,755 ÷ 4 = 1,001,188.75
If the quotient is a whole number, then 4 and 1,001,188.75 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 | 4,004,755 | |
| -1 | 4,004,755 |
If you did it right, you will end up with this table:
| 1 | 5 | 29 | 71 | 145 | 355 | 389 | 1,945 | 2,059 | 10,295 | 11,281 | 27,619 | 56,405 | 138,095 | 800,951 | 4,004,755 |
| -1 | -5 | -29 | -71 | -145 | -355 | -389 | -1,945 | -2,059 | -10,295 | -11,281 | -27,619 | -56,405 | -138,095 | -800,951 | -4,004,755 |
