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 23,961,619, 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 | 23,961,619 | |
| -1 | -23,961,619 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 23,961,619.
Example:
1 x 23,961,619 = 23,961,619
and
-1 x -23,961,619 = 23,961,619
Notice both answers equal 23,961,619
With that explanation out of the way, let's continue. Next, we take the number 23,961,619 and divide it by 2:
23,961,619 ÷ 2 = 11,980,809.5
If the quotient is a whole number, then 2 and 11,980,809.5 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 | 23,961,619 | |
| -1 | -23,961,619 |
Now, we try dividing 23,961,619 by 3:
23,961,619 ÷ 3 = 7,987,206.3333
If the quotient is a whole number, then 3 and 7,987,206.3333 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 | 23,961,619 | |
| -1 | -23,961,619 |
Let's try dividing by 4:
23,961,619 ÷ 4 = 5,990,404.75
If the quotient is a whole number, then 4 and 5,990,404.75 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 | 23,961,619 | |
| -1 | 23,961,619 |
If you did it right, you will end up with this table:
| 1 | 11 | 17 | 97 | 187 | 1,067 | 1,321 | 1,649 | 14,531 | 18,139 | 22,457 | 128,137 | 247,027 | 1,409,507 | 2,178,329 | 23,961,619 |
| -1 | -11 | -17 | -97 | -187 | -1,067 | -1,321 | -1,649 | -14,531 | -18,139 | -22,457 | -128,137 | -247,027 | -1,409,507 | -2,178,329 | -23,961,619 |
