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 23,956,225, 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 | 23,956,225 | |
| -1 | -23,956,225 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 23,956,225.
Example:
1 x 23,956,225 = 23,956,225
and
-1 x -23,956,225 = 23,956,225
Notice both answers equal 23,956,225
With that explanation out of the way, let's continue. Next, we take the number 23,956,225 and divide it by 2:
23,956,225 ÷ 2 = 11,978,112.5
If the quotient is a whole number, then 2 and 11,978,112.5 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 | 23,956,225 | |
| -1 | -23,956,225 |
Now, we try dividing 23,956,225 by 3:
23,956,225 ÷ 3 = 7,985,408.3333
If the quotient is a whole number, then 3 and 7,985,408.3333 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 | 23,956,225 | |
| -1 | -23,956,225 |
Let's try dividing by 4:
23,956,225 ÷ 4 = 5,989,056.25
If the quotient is a whole number, then 4 and 5,989,056.25 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 | 23,956,225 | |
| -1 | 23,956,225 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 25 | 61 | 115 | 305 | 575 | 683 | 1,403 | 1,525 | 3,415 | 7,015 | 15,709 | 17,075 | 35,075 | 41,663 | 78,545 | 208,315 | 392,725 | 958,249 | 1,041,575 | 4,791,245 | 23,956,225 |
| -1 | -5 | -23 | -25 | -61 | -115 | -305 | -575 | -683 | -1,403 | -1,525 | -3,415 | -7,015 | -15,709 | -17,075 | -35,075 | -41,663 | -78,545 | -208,315 | -392,725 | -958,249 | -1,041,575 | -4,791,245 | -23,956,225 |
