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 3,320,503, 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 | 3,320,503 | |
| -1 | -3,320,503 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,320,503.
Example:
1 x 3,320,503 = 3,320,503
and
-1 x -3,320,503 = 3,320,503
Notice both answers equal 3,320,503
With that explanation out of the way, let's continue. Next, we take the number 3,320,503 and divide it by 2:
3,320,503 ÷ 2 = 1,660,251.5
If the quotient is a whole number, then 2 and 1,660,251.5 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 | 3,320,503 | |
| -1 | -3,320,503 |
Now, we try dividing 3,320,503 by 3:
3,320,503 ÷ 3 = 1,106,834.3333
If the quotient is a whole number, then 3 and 1,106,834.3333 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 | 3,320,503 | |
| -1 | -3,320,503 |
Let's try dividing by 4:
3,320,503 ÷ 4 = 830,125.75
If the quotient is a whole number, then 4 and 830,125.75 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 | 3,320,503 | |
| -1 | 3,320,503 |
If you did it right, you will end up with this table:
| 1 | 31 | 43 | 47 | 53 | 1,333 | 1,457 | 1,643 | 2,021 | 2,279 | 2,491 | 62,651 | 70,649 | 77,221 | 107,113 | 3,320,503 |
| -1 | -31 | -43 | -47 | -53 | -1,333 | -1,457 | -1,643 | -2,021 | -2,279 | -2,491 | -62,651 | -70,649 | -77,221 | -107,113 | -3,320,503 |
