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 4,003,405, 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 | 4,003,405 | |
| -1 | -4,003,405 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 4,003,405.
Example:
1 x 4,003,405 = 4,003,405
and
-1 x -4,003,405 = 4,003,405
Notice both answers equal 4,003,405
With that explanation out of the way, let's continue. Next, we take the number 4,003,405 and divide it by 2:
4,003,405 ÷ 2 = 2,001,702.5
If the quotient is a whole number, then 2 and 2,001,702.5 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 | 4,003,405 | |
| -1 | -4,003,405 |
Now, we try dividing 4,003,405 by 3:
4,003,405 ÷ 3 = 1,334,468.3333
If the quotient is a whole number, then 3 and 1,334,468.3333 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 | 4,003,405 | |
| -1 | -4,003,405 |
Let's try dividing by 4:
4,003,405 ÷ 4 = 1,000,851.25
If the quotient is a whole number, then 4 and 1,000,851.25 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 | 4,003,405 | |
| -1 | 4,003,405 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 107 | 535 | 749 | 1,069 | 3,745 | 5,345 | 7,483 | 37,415 | 114,383 | 571,915 | 800,681 | 4,003,405 |
| -1 | -5 | -7 | -35 | -107 | -535 | -749 | -1,069 | -3,745 | -5,345 | -7,483 | -37,415 | -114,383 | -571,915 | -800,681 | -4,003,405 |
