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 7,406,803, 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 | 7,406,803 | |
| -1 | -7,406,803 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 7,406,803.
Example:
1 x 7,406,803 = 7,406,803
and
-1 x -7,406,803 = 7,406,803
Notice both answers equal 7,406,803
With that explanation out of the way, let's continue. Next, we take the number 7,406,803 and divide it by 2:
7,406,803 ÷ 2 = 3,703,401.5
If the quotient is a whole number, then 2 and 3,703,401.5 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 | 7,406,803 | |
| -1 | -7,406,803 |
Now, we try dividing 7,406,803 by 3:
7,406,803 ÷ 3 = 2,468,934.3333
If the quotient is a whole number, then 3 and 2,468,934.3333 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 | 7,406,803 | |
| -1 | -7,406,803 |
Let's try dividing by 4:
7,406,803 ÷ 4 = 1,851,700.75
If the quotient is a whole number, then 4 and 1,851,700.75 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 | 7,406,803 | |
| -1 | 7,406,803 |
If you did it right, you will end up with this table:
| 1 | 29 | 53 | 61 | 79 | 1,537 | 1,769 | 2,291 | 3,233 | 4,187 | 4,819 | 93,757 | 121,423 | 139,751 | 255,407 | 7,406,803 |
| -1 | -29 | -53 | -61 | -79 | -1,537 | -1,769 | -2,291 | -3,233 | -4,187 | -4,819 | -93,757 | -121,423 | -139,751 | -255,407 | -7,406,803 |
