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 23,318,779, 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 | 23,318,779 | |
| -1 | -23,318,779 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 23,318,779.
Example:
1 x 23,318,779 = 23,318,779
and
-1 x -23,318,779 = 23,318,779
Notice both answers equal 23,318,779
With that explanation out of the way, let's continue. Next, we take the number 23,318,779 and divide it by 2:
23,318,779 ÷ 2 = 11,659,389.5
If the quotient is a whole number, then 2 and 11,659,389.5 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 | 23,318,779 | |
| -1 | -23,318,779 |
Now, we try dividing 23,318,779 by 3:
23,318,779 ÷ 3 = 7,772,926.3333
If the quotient is a whole number, then 3 and 7,772,926.3333 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 | 23,318,779 | |
| -1 | -23,318,779 |
Let's try dividing by 4:
23,318,779 ÷ 4 = 5,829,694.75
If the quotient is a whole number, then 4 and 5,829,694.75 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 | 23,318,779 | |
| -1 | 23,318,779 |
If you did it right, you will end up with this table:
| 1 | 11 | 101 | 139 | 151 | 1,111 | 1,529 | 1,661 | 14,039 | 15,251 | 20,989 | 154,429 | 167,761 | 230,879 | 2,119,889 | 23,318,779 |
| -1 | -11 | -101 | -139 | -151 | -1,111 | -1,529 | -1,661 | -14,039 | -15,251 | -20,989 | -154,429 | -167,761 | -230,879 | -2,119,889 | -23,318,779 |
