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 30,411,343, 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 | 30,411,343 | |
| -1 | -30,411,343 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 30,411,343.
Example:
1 x 30,411,343 = 30,411,343
and
-1 x -30,411,343 = 30,411,343
Notice both answers equal 30,411,343
With that explanation out of the way, let's continue. Next, we take the number 30,411,343 and divide it by 2:
30,411,343 ÷ 2 = 15,205,671.5
If the quotient is a whole number, then 2 and 15,205,671.5 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 | 30,411,343 | |
| -1 | -30,411,343 |
Now, we try dividing 30,411,343 by 3:
30,411,343 ÷ 3 = 10,137,114.3333
If the quotient is a whole number, then 3 and 10,137,114.3333 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 | 30,411,343 | |
| -1 | -30,411,343 |
Let's try dividing by 4:
30,411,343 ÷ 4 = 7,602,835.75
If the quotient is a whole number, then 4 and 7,602,835.75 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 | 30,411,343 | |
| -1 | 30,411,343 |
If you did it right, you will end up with this table:
| 1 | 19 | 29 | 97 | 551 | 569 | 1,843 | 2,813 | 10,811 | 16,501 | 53,447 | 55,193 | 313,519 | 1,048,667 | 1,600,597 | 30,411,343 |
| -1 | -19 | -29 | -97 | -551 | -569 | -1,843 | -2,813 | -10,811 | -16,501 | -53,447 | -55,193 | -313,519 | -1,048,667 | -1,600,597 | -30,411,343 |
