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 29,902,243, 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 | 29,902,243 | |
| -1 | -29,902,243 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 29,902,243.
Example:
1 x 29,902,243 = 29,902,243
and
-1 x -29,902,243 = 29,902,243
Notice both answers equal 29,902,243
With that explanation out of the way, let's continue. Next, we take the number 29,902,243 and divide it by 2:
29,902,243 ÷ 2 = 14,951,121.5
If the quotient is a whole number, then 2 and 14,951,121.5 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 | 29,902,243 | |
| -1 | -29,902,243 |
Now, we try dividing 29,902,243 by 3:
29,902,243 ÷ 3 = 9,967,414.3333
If the quotient is a whole number, then 3 and 9,967,414.3333 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 | 29,902,243 | |
| -1 | -29,902,243 |
Let's try dividing by 4:
29,902,243 ÷ 4 = 7,475,560.75
If the quotient is a whole number, then 4 and 7,475,560.75 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 | 29,902,243 | |
| -1 | 29,902,243 |
If you did it right, you will end up with this table:
| 1 | 7 | 41 | 43 | 287 | 301 | 1,763 | 2,423 | 12,341 | 16,961 | 99,343 | 104,189 | 695,401 | 729,323 | 4,271,749 | 29,902,243 |
| -1 | -7 | -41 | -43 | -287 | -301 | -1,763 | -2,423 | -12,341 | -16,961 | -99,343 | -104,189 | -695,401 | -729,323 | -4,271,749 | -29,902,243 |
