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 24,608,401, 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 | 24,608,401 | |
| -1 | -24,608,401 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 24,608,401.
Example:
1 x 24,608,401 = 24,608,401
and
-1 x -24,608,401 = 24,608,401
Notice both answers equal 24,608,401
With that explanation out of the way, let's continue. Next, we take the number 24,608,401 and divide it by 2:
24,608,401 ÷ 2 = 12,304,200.5
If the quotient is a whole number, then 2 and 12,304,200.5 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 | 24,608,401 | |
| -1 | -24,608,401 |
Now, we try dividing 24,608,401 by 3:
24,608,401 ÷ 3 = 8,202,800.3333
If the quotient is a whole number, then 3 and 8,202,800.3333 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 | 24,608,401 | |
| -1 | -24,608,401 |
Let's try dividing by 4:
24,608,401 ÷ 4 = 6,152,100.25
If the quotient is a whole number, then 4 and 6,152,100.25 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 | 24,608,401 | |
| -1 | 24,608,401 |
If you did it right, you will end up with this table:
| 1 | 17 | 19 | 47 | 323 | 799 | 893 | 1,621 | 15,181 | 27,557 | 30,799 | 76,187 | 523,583 | 1,295,179 | 1,447,553 | 24,608,401 |
| -1 | -17 | -19 | -47 | -323 | -799 | -893 | -1,621 | -15,181 | -27,557 | -30,799 | -76,187 | -523,583 | -1,295,179 | -1,447,553 | -24,608,401 |
