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 24,396,701, 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 | 24,396,701 | |
| -1 | -24,396,701 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 24,396,701.
Example:
1 x 24,396,701 = 24,396,701
and
-1 x -24,396,701 = 24,396,701
Notice both answers equal 24,396,701
With that explanation out of the way, let's continue. Next, we take the number 24,396,701 and divide it by 2:
24,396,701 ÷ 2 = 12,198,350.5
If the quotient is a whole number, then 2 and 12,198,350.5 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 | 24,396,701 | |
| -1 | -24,396,701 |
Now, we try dividing 24,396,701 by 3:
24,396,701 ÷ 3 = 8,132,233.6667
If the quotient is a whole number, then 3 and 8,132,233.6667 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 | 24,396,701 | |
| -1 | -24,396,701 |
Let's try dividing by 4:
24,396,701 ÷ 4 = 6,099,175.25
If the quotient is a whole number, then 4 and 6,099,175.25 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 | 24,396,701 | |
| -1 | 24,396,701 |
If you did it right, you will end up with this table:
| 1 | 7 | 79 | 157 | 281 | 553 | 1,099 | 1,967 | 12,403 | 22,199 | 44,117 | 86,821 | 155,393 | 308,819 | 3,485,243 | 24,396,701 |
| -1 | -7 | -79 | -157 | -281 | -553 | -1,099 | -1,967 | -12,403 | -22,199 | -44,117 | -86,821 | -155,393 | -308,819 | -3,485,243 | -24,396,701 |
