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 23,895,863, 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 | 23,895,863 | |
| -1 | -23,895,863 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 23,895,863.
Example:
1 x 23,895,863 = 23,895,863
and
-1 x -23,895,863 = 23,895,863
Notice both answers equal 23,895,863
With that explanation out of the way, let's continue. Next, we take the number 23,895,863 and divide it by 2:
23,895,863 ÷ 2 = 11,947,931.5
If the quotient is a whole number, then 2 and 11,947,931.5 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 | 23,895,863 | |
| -1 | -23,895,863 |
Now, we try dividing 23,895,863 by 3:
23,895,863 ÷ 3 = 7,965,287.6667
If the quotient is a whole number, then 3 and 7,965,287.6667 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 | 23,895,863 | |
| -1 | -23,895,863 |
Let's try dividing by 4:
23,895,863 ÷ 4 = 5,973,965.75
If the quotient is a whole number, then 4 and 5,973,965.75 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 | 23,895,863 | |
| -1 | 23,895,863 |
If you did it right, you will end up with this table:
| 1 | 17 | 19 | 167 | 323 | 443 | 2,839 | 3,173 | 7,531 | 8,417 | 53,941 | 73,981 | 143,089 | 1,257,677 | 1,405,639 | 23,895,863 |
| -1 | -17 | -19 | -167 | -323 | -443 | -2,839 | -3,173 | -7,531 | -8,417 | -53,941 | -73,981 | -143,089 | -1,257,677 | -1,405,639 | -23,895,863 |
