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 30,829,211, 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 | 30,829,211 | |
| -1 | -30,829,211 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 30,829,211.
Example:
1 x 30,829,211 = 30,829,211
and
-1 x -30,829,211 = 30,829,211
Notice both answers equal 30,829,211
With that explanation out of the way, let's continue. Next, we take the number 30,829,211 and divide it by 2:
30,829,211 ÷ 2 = 15,414,605.5
If the quotient is a whole number, then 2 and 15,414,605.5 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 | 30,829,211 | |
| -1 | -30,829,211 |
Now, we try dividing 30,829,211 by 3:
30,829,211 ÷ 3 = 10,276,403.6667
If the quotient is a whole number, then 3 and 10,276,403.6667 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 | 30,829,211 | |
| -1 | -30,829,211 |
Let's try dividing by 4:
30,829,211 ÷ 4 = 7,707,302.75
If the quotient is a whole number, then 4 and 7,707,302.75 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 | 30,829,211 | |
| -1 | 30,829,211 |
If you did it right, you will end up with this table:
| 1 | 7 | 17 | 59 | 119 | 413 | 1,003 | 4,391 | 7,021 | 30,737 | 74,647 | 259,069 | 522,529 | 1,813,483 | 4,404,173 | 30,829,211 |
| -1 | -7 | -17 | -59 | -119 | -413 | -1,003 | -4,391 | -7,021 | -30,737 | -74,647 | -259,069 | -522,529 | -1,813,483 | -4,404,173 | -30,829,211 |
