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 4,005,875, 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 | 4,005,875 | |
| -1 | -4,005,875 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 4,005,875.
Example:
1 x 4,005,875 = 4,005,875
and
-1 x -4,005,875 = 4,005,875
Notice both answers equal 4,005,875
With that explanation out of the way, let's continue. Next, we take the number 4,005,875 and divide it by 2:
4,005,875 ÷ 2 = 2,002,937.5
If the quotient is a whole number, then 2 and 2,002,937.5 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 | 4,005,875 | |
| -1 | -4,005,875 |
Now, we try dividing 4,005,875 by 3:
4,005,875 ÷ 3 = 1,335,291.6667
If the quotient is a whole number, then 3 and 1,335,291.6667 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 | 4,005,875 | |
| -1 | -4,005,875 |
Let's try dividing by 4:
4,005,875 ÷ 4 = 1,001,468.75
If the quotient is a whole number, then 4 and 1,001,468.75 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 | 4,005,875 | |
| -1 | 4,005,875 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 73 | 125 | 365 | 439 | 1,825 | 2,195 | 9,125 | 10,975 | 32,047 | 54,875 | 160,235 | 801,175 | 4,005,875 |
| -1 | -5 | -25 | -73 | -125 | -365 | -439 | -1,825 | -2,195 | -9,125 | -10,975 | -32,047 | -54,875 | -160,235 | -801,175 | -4,005,875 |
