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 7,300,123, 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 | 7,300,123 | |
| -1 | -7,300,123 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 7,300,123.
Example:
1 x 7,300,123 = 7,300,123
and
-1 x -7,300,123 = 7,300,123
Notice both answers equal 7,300,123
With that explanation out of the way, let's continue. Next, we take the number 7,300,123 and divide it by 2:
7,300,123 ÷ 2 = 3,650,061.5
If the quotient is a whole number, then 2 and 3,650,061.5 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 | 7,300,123 | |
| -1 | -7,300,123 |
Now, we try dividing 7,300,123 by 3:
7,300,123 ÷ 3 = 2,433,374.3333
If the quotient is a whole number, then 3 and 2,433,374.3333 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 | 7,300,123 | |
| -1 | -7,300,123 |
Let's try dividing by 4:
7,300,123 ÷ 4 = 1,825,030.75
If the quotient is a whole number, then 4 and 1,825,030.75 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 | 7,300,123 | |
| -1 | 7,300,123 |
If you did it right, you will end up with this table:
| 1 | 17 | 19 | 97 | 233 | 323 | 1,649 | 1,843 | 3,961 | 4,427 | 22,601 | 31,331 | 75,259 | 384,217 | 429,419 | 7,300,123 |
| -1 | -17 | -19 | -97 | -233 | -323 | -1,649 | -1,843 | -3,961 | -4,427 | -22,601 | -31,331 | -75,259 | -384,217 | -429,419 | -7,300,123 |
