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 23,783,711, 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 | 23,783,711 | |
| -1 | -23,783,711 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 23,783,711.
Example:
1 x 23,783,711 = 23,783,711
and
-1 x -23,783,711 = 23,783,711
Notice both answers equal 23,783,711
With that explanation out of the way, let's continue. Next, we take the number 23,783,711 and divide it by 2:
23,783,711 ÷ 2 = 11,891,855.5
If the quotient is a whole number, then 2 and 11,891,855.5 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 | 23,783,711 | |
| -1 | -23,783,711 |
Now, we try dividing 23,783,711 by 3:
23,783,711 ÷ 3 = 7,927,903.6667
If the quotient is a whole number, then 3 and 7,927,903.6667 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 | 23,783,711 | |
| -1 | -23,783,711 |
Let's try dividing by 4:
23,783,711 ÷ 4 = 5,945,927.75
If the quotient is a whole number, then 4 and 5,945,927.75 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 | 23,783,711 | |
| -1 | 23,783,711 |
If you did it right, you will end up with this table:
| 1 | 7 | 37 | 229 | 259 | 401 | 1,603 | 2,807 | 8,473 | 14,837 | 59,311 | 91,829 | 103,859 | 642,803 | 3,397,673 | 23,783,711 |
| -1 | -7 | -37 | -229 | -259 | -401 | -1,603 | -2,807 | -8,473 | -14,837 | -59,311 | -91,829 | -103,859 | -642,803 | -3,397,673 | -23,783,711 |
