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 23,438,311, 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 | 23,438,311 | |
| -1 | -23,438,311 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 23,438,311.
Example:
1 x 23,438,311 = 23,438,311
and
-1 x -23,438,311 = 23,438,311
Notice both answers equal 23,438,311
With that explanation out of the way, let's continue. Next, we take the number 23,438,311 and divide it by 2:
23,438,311 ÷ 2 = 11,719,155.5
If the quotient is a whole number, then 2 and 11,719,155.5 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 | 23,438,311 | |
| -1 | -23,438,311 |
Now, we try dividing 23,438,311 by 3:
23,438,311 ÷ 3 = 7,812,770.3333
If the quotient is a whole number, then 3 and 7,812,770.3333 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 | 23,438,311 | |
| -1 | -23,438,311 |
Let's try dividing by 4:
23,438,311 ÷ 4 = 5,859,577.75
If the quotient is a whole number, then 4 and 5,859,577.75 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 | 23,438,311 | |
| -1 | 23,438,311 |
If you did it right, you will end up with this table:
| 1 | 13 | 23 | 43 | 299 | 559 | 989 | 1,823 | 12,857 | 23,699 | 41,929 | 78,389 | 545,077 | 1,019,057 | 1,802,947 | 23,438,311 |
| -1 | -13 | -23 | -43 | -299 | -559 | -989 | -1,823 | -12,857 | -23,699 | -41,929 | -78,389 | -545,077 | -1,019,057 | -1,802,947 | -23,438,311 |
