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 24,201,815, 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 | 24,201,815 | |
| -1 | -24,201,815 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 24,201,815.
Example:
1 x 24,201,815 = 24,201,815
and
-1 x -24,201,815 = 24,201,815
Notice both answers equal 24,201,815
With that explanation out of the way, let's continue. Next, we take the number 24,201,815 and divide it by 2:
24,201,815 ÷ 2 = 12,100,907.5
If the quotient is a whole number, then 2 and 12,100,907.5 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 | 24,201,815 | |
| -1 | -24,201,815 |
Now, we try dividing 24,201,815 by 3:
24,201,815 ÷ 3 = 8,067,271.6667
If the quotient is a whole number, then 3 and 8,067,271.6667 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 | 24,201,815 | |
| -1 | -24,201,815 |
Let's try dividing by 4:
24,201,815 ÷ 4 = 6,050,453.75
If the quotient is a whole number, then 4 and 6,050,453.75 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 | 24,201,815 | |
| -1 | 24,201,815 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 109 | 121 | 367 | 545 | 605 | 1,199 | 1,835 | 4,037 | 5,995 | 13,189 | 20,185 | 40,003 | 44,407 | 65,945 | 200,015 | 222,035 | 440,033 | 2,200,165 | 4,840,363 | 24,201,815 |
| -1 | -5 | -11 | -55 | -109 | -121 | -367 | -545 | -605 | -1,199 | -1,835 | -4,037 | -5,995 | -13,189 | -20,185 | -40,003 | -44,407 | -65,945 | -200,015 | -222,035 | -440,033 | -2,200,165 | -4,840,363 | -24,201,815 |
