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 5,030,123, 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 | 5,030,123 | |
| -1 | -5,030,123 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 5,030,123.
Example:
1 x 5,030,123 = 5,030,123
and
-1 x -5,030,123 = 5,030,123
Notice both answers equal 5,030,123
With that explanation out of the way, let's continue. Next, we take the number 5,030,123 and divide it by 2:
5,030,123 ÷ 2 = 2,515,061.5
If the quotient is a whole number, then 2 and 2,515,061.5 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 | 5,030,123 | |
| -1 | -5,030,123 |
Now, we try dividing 5,030,123 by 3:
5,030,123 ÷ 3 = 1,676,707.6667
If the quotient is a whole number, then 3 and 1,676,707.6667 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 | 5,030,123 | |
| -1 | -5,030,123 |
Let's try dividing by 4:
5,030,123 ÷ 4 = 1,257,530.75
If the quotient is a whole number, then 4 and 1,257,530.75 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 | 5,030,123 | |
| -1 | 5,030,123 |
If you did it right, you will end up with this table:
| 1 | 7 | 23 | 157 | 161 | 199 | 1,099 | 1,393 | 3,611 | 4,577 | 25,277 | 31,243 | 32,039 | 218,701 | 718,589 | 5,030,123 |
| -1 | -7 | -23 | -157 | -161 | -199 | -1,099 | -1,393 | -3,611 | -4,577 | -25,277 | -31,243 | -32,039 | -218,701 | -718,589 | -5,030,123 |
