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 3,540,403, 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 | 3,540,403 | |
| -1 | -3,540,403 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,540,403.
Example:
1 x 3,540,403 = 3,540,403
and
-1 x -3,540,403 = 3,540,403
Notice both answers equal 3,540,403
With that explanation out of the way, let's continue. Next, we take the number 3,540,403 and divide it by 2:
3,540,403 ÷ 2 = 1,770,201.5
If the quotient is a whole number, then 2 and 1,770,201.5 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 | 3,540,403 | |
| -1 | -3,540,403 |
Now, we try dividing 3,540,403 by 3:
3,540,403 ÷ 3 = 1,180,134.3333
If the quotient is a whole number, then 3 and 1,180,134.3333 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 | 3,540,403 | |
| -1 | -3,540,403 |
Let's try dividing by 4:
3,540,403 ÷ 4 = 885,100.75
If the quotient is a whole number, then 4 and 885,100.75 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 | 3,540,403 | |
| -1 | 3,540,403 |
If you did it right, you will end up with this table:
| 1 | 17 | 19 | 97 | 113 | 323 | 1,649 | 1,843 | 1,921 | 2,147 | 10,961 | 31,331 | 36,499 | 186,337 | 208,259 | 3,540,403 |
| -1 | -17 | -19 | -97 | -113 | -323 | -1,649 | -1,843 | -1,921 | -2,147 | -10,961 | -31,331 | -36,499 | -186,337 | -208,259 | -3,540,403 |
