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 4,004,375, 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 | 4,004,375 | |
| -1 | -4,004,375 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 4,004,375.
Example:
1 x 4,004,375 = 4,004,375
and
-1 x -4,004,375 = 4,004,375
Notice both answers equal 4,004,375
With that explanation out of the way, let's continue. Next, we take the number 4,004,375 and divide it by 2:
4,004,375 ÷ 2 = 2,002,187.5
If the quotient is a whole number, then 2 and 2,002,187.5 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 | 4,004,375 | |
| -1 | -4,004,375 |
Now, we try dividing 4,004,375 by 3:
4,004,375 ÷ 3 = 1,334,791.6667
If the quotient is a whole number, then 3 and 1,334,791.6667 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 | 4,004,375 | |
| -1 | -4,004,375 |
Let's try dividing by 4:
4,004,375 ÷ 4 = 1,001,093.75
If the quotient is a whole number, then 4 and 1,001,093.75 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 | 4,004,375 | |
| -1 | 4,004,375 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 43 | 125 | 149 | 215 | 625 | 745 | 1,075 | 3,725 | 5,375 | 6,407 | 18,625 | 26,875 | 32,035 | 93,125 | 160,175 | 800,875 | 4,004,375 |
| -1 | -5 | -25 | -43 | -125 | -149 | -215 | -625 | -745 | -1,075 | -3,725 | -5,375 | -6,407 | -18,625 | -26,875 | -32,035 | -93,125 | -160,175 | -800,875 | -4,004,375 |
