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 24,120,671, 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 | 24,120,671 | |
| -1 | -24,120,671 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 24,120,671.
Example:
1 x 24,120,671 = 24,120,671
and
-1 x -24,120,671 = 24,120,671
Notice both answers equal 24,120,671
With that explanation out of the way, let's continue. Next, we take the number 24,120,671 and divide it by 2:
24,120,671 ÷ 2 = 12,060,335.5
If the quotient is a whole number, then 2 and 12,060,335.5 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 | 24,120,671 | |
| -1 | -24,120,671 |
Now, we try dividing 24,120,671 by 3:
24,120,671 ÷ 3 = 8,040,223.6667
If the quotient is a whole number, then 3 and 8,040,223.6667 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 | 24,120,671 | |
| -1 | -24,120,671 |
Let's try dividing by 4:
24,120,671 ÷ 4 = 6,030,167.75
If the quotient is a whole number, then 4 and 6,030,167.75 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 | 24,120,671 | |
| -1 | 24,120,671 |
If you did it right, you will end up with this table:
| 1 | 17 | 19 | 53 | 323 | 901 | 1,007 | 1,409 | 17,119 | 23,953 | 26,771 | 74,677 | 455,107 | 1,269,509 | 1,418,863 | 24,120,671 |
| -1 | -17 | -19 | -53 | -323 | -901 | -1,007 | -1,409 | -17,119 | -23,953 | -26,771 | -74,677 | -455,107 | -1,269,509 | -1,418,863 | -24,120,671 |
