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 23,114,425, 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 | 23,114,425 | |
| -1 | -23,114,425 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 23,114,425.
Example:
1 x 23,114,425 = 23,114,425
and
-1 x -23,114,425 = 23,114,425
Notice both answers equal 23,114,425
With that explanation out of the way, let's continue. Next, we take the number 23,114,425 and divide it by 2:
23,114,425 ÷ 2 = 11,557,212.5
If the quotient is a whole number, then 2 and 11,557,212.5 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 | 23,114,425 | |
| -1 | -23,114,425 |
Now, we try dividing 23,114,425 by 3:
23,114,425 ÷ 3 = 7,704,808.3333
If the quotient is a whole number, then 3 and 7,704,808.3333 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 | 23,114,425 | |
| -1 | -23,114,425 |
Let's try dividing by 4:
23,114,425 ÷ 4 = 5,778,606.25
If the quotient is a whole number, then 4 and 5,778,606.25 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 | 23,114,425 | |
| -1 | 23,114,425 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 25 | 61 | 115 | 305 | 575 | 659 | 1,403 | 1,525 | 3,295 | 7,015 | 15,157 | 16,475 | 35,075 | 40,199 | 75,785 | 200,995 | 378,925 | 924,577 | 1,004,975 | 4,622,885 | 23,114,425 |
| -1 | -5 | -23 | -25 | -61 | -115 | -305 | -575 | -659 | -1,403 | -1,525 | -3,295 | -7,015 | -15,157 | -16,475 | -35,075 | -40,199 | -75,785 | -200,995 | -378,925 | -924,577 | -1,004,975 | -4,622,885 | -23,114,425 |
