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 23,404,409, 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 | 23,404,409 | |
| -1 | -23,404,409 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 23,404,409.
Example:
1 x 23,404,409 = 23,404,409
and
-1 x -23,404,409 = 23,404,409
Notice both answers equal 23,404,409
With that explanation out of the way, let's continue. Next, we take the number 23,404,409 and divide it by 2:
23,404,409 ÷ 2 = 11,702,204.5
If the quotient is a whole number, then 2 and 11,702,204.5 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 | 23,404,409 | |
| -1 | -23,404,409 |
Now, we try dividing 23,404,409 by 3:
23,404,409 ÷ 3 = 7,801,469.6667
If the quotient is a whole number, then 3 and 7,801,469.6667 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 | 23,404,409 | |
| -1 | -23,404,409 |
Let's try dividing by 4:
23,404,409 ÷ 4 = 5,851,102.25
If the quotient is a whole number, then 4 and 5,851,102.25 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 | 23,404,409 | |
| -1 | 23,404,409 |
If you did it right, you will end up with this table:
| 1 | 7 | 19 | 23 | 49 | 133 | 161 | 437 | 931 | 1,093 | 1,127 | 3,059 | 7,651 | 20,767 | 21,413 | 25,139 | 53,557 | 145,369 | 175,973 | 477,641 | 1,017,583 | 1,231,811 | 3,343,487 | 23,404,409 |
| -1 | -7 | -19 | -23 | -49 | -133 | -161 | -437 | -931 | -1,093 | -1,127 | -3,059 | -7,651 | -20,767 | -21,413 | -25,139 | -53,557 | -145,369 | -175,973 | -477,641 | -1,017,583 | -1,231,811 | -3,343,487 | -23,404,409 |
