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 24,300,311, 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 | 24,300,311 | |
| -1 | -24,300,311 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 24,300,311.
Example:
1 x 24,300,311 = 24,300,311
and
-1 x -24,300,311 = 24,300,311
Notice both answers equal 24,300,311
With that explanation out of the way, let's continue. Next, we take the number 24,300,311 and divide it by 2:
24,300,311 ÷ 2 = 12,150,155.5
If the quotient is a whole number, then 2 and 12,150,155.5 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 | 24,300,311 | |
| -1 | -24,300,311 |
Now, we try dividing 24,300,311 by 3:
24,300,311 ÷ 3 = 8,100,103.6667
If the quotient is a whole number, then 3 and 8,100,103.6667 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 | 24,300,311 | |
| -1 | -24,300,311 |
Let's try dividing by 4:
24,300,311 ÷ 4 = 6,075,077.75
If the quotient is a whole number, then 4 and 6,075,077.75 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 | 24,300,311 | |
| -1 | 24,300,311 |
If you did it right, you will end up with this table:
| 1 | 7 | 31 | 113 | 217 | 791 | 991 | 3,503 | 6,937 | 24,521 | 30,721 | 111,983 | 215,047 | 783,881 | 3,471,473 | 24,300,311 |
| -1 | -7 | -31 | -113 | -217 | -791 | -991 | -3,503 | -6,937 | -24,521 | -30,721 | -111,983 | -215,047 | -783,881 | -3,471,473 | -24,300,311 |
