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 23,401,405, 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 | 23,401,405 | |
| -1 | -23,401,405 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 23,401,405.
Example:
1 x 23,401,405 = 23,401,405
and
-1 x -23,401,405 = 23,401,405
Notice both answers equal 23,401,405
With that explanation out of the way, let's continue. Next, we take the number 23,401,405 and divide it by 2:
23,401,405 ÷ 2 = 11,700,702.5
If the quotient is a whole number, then 2 and 11,700,702.5 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 | 23,401,405 | |
| -1 | -23,401,405 |
Now, we try dividing 23,401,405 by 3:
23,401,405 ÷ 3 = 7,800,468.3333
If the quotient is a whole number, then 3 and 7,800,468.3333 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 | 23,401,405 | |
| -1 | -23,401,405 |
Let's try dividing by 4:
23,401,405 ÷ 4 = 5,850,351.25
If the quotient is a whole number, then 4 and 5,850,351.25 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 | 23,401,405 | |
| -1 | 23,401,405 |
If you did it right, you will end up with this table:
| 1 | 5 | 29 | 145 | 199 | 811 | 995 | 4,055 | 5,771 | 23,519 | 28,855 | 117,595 | 161,389 | 806,945 | 4,680,281 | 23,401,405 |
| -1 | -5 | -29 | -145 | -199 | -811 | -995 | -4,055 | -5,771 | -23,519 | -28,855 | -117,595 | -161,389 | -806,945 | -4,680,281 | -23,401,405 |
