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 24,118,171, 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 | 24,118,171 | |
| -1 | -24,118,171 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 24,118,171.
Example:
1 x 24,118,171 = 24,118,171
and
-1 x -24,118,171 = 24,118,171
Notice both answers equal 24,118,171
With that explanation out of the way, let's continue. Next, we take the number 24,118,171 and divide it by 2:
24,118,171 ÷ 2 = 12,059,085.5
If the quotient is a whole number, then 2 and 12,059,085.5 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 | 24,118,171 | |
| -1 | -24,118,171 |
Now, we try dividing 24,118,171 by 3:
24,118,171 ÷ 3 = 8,039,390.3333
If the quotient is a whole number, then 3 and 8,039,390.3333 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 | 24,118,171 | |
| -1 | -24,118,171 |
Let's try dividing by 4:
24,118,171 ÷ 4 = 6,029,542.75
If the quotient is a whole number, then 4 and 6,029,542.75 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 | 24,118,171 | |
| -1 | 24,118,171 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 77 | 103 | 721 | 1,133 | 3,041 | 7,931 | 21,287 | 33,451 | 234,157 | 313,223 | 2,192,561 | 3,445,453 | 24,118,171 |
| -1 | -7 | -11 | -77 | -103 | -721 | -1,133 | -3,041 | -7,931 | -21,287 | -33,451 | -234,157 | -313,223 | -2,192,561 | -3,445,453 | -24,118,171 |
