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 24,467,777, 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 | 24,467,777 | |
| -1 | -24,467,777 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 24,467,777.
Example:
1 x 24,467,777 = 24,467,777
and
-1 x -24,467,777 = 24,467,777
Notice both answers equal 24,467,777
With that explanation out of the way, let's continue. Next, we take the number 24,467,777 and divide it by 2:
24,467,777 ÷ 2 = 12,233,888.5
If the quotient is a whole number, then 2 and 12,233,888.5 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 | 24,467,777 | |
| -1 | -24,467,777 |
Now, we try dividing 24,467,777 by 3:
24,467,777 ÷ 3 = 8,155,925.6667
If the quotient is a whole number, then 3 and 8,155,925.6667 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 | 24,467,777 | |
| -1 | -24,467,777 |
Let's try dividing by 4:
24,467,777 ÷ 4 = 6,116,944.25
If the quotient is a whole number, then 4 and 6,116,944.25 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 | 24,467,777 | |
| -1 | 24,467,777 |
If you did it right, you will end up with this table:
| 1 | 17 | 47 | 113 | 271 | 799 | 1,921 | 4,607 | 5,311 | 12,737 | 30,623 | 90,287 | 216,529 | 520,591 | 1,439,281 | 24,467,777 |
| -1 | -17 | -47 | -113 | -271 | -799 | -1,921 | -4,607 | -5,311 | -12,737 | -30,623 | -90,287 | -216,529 | -520,591 | -1,439,281 | -24,467,777 |
