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 30,242,201, 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 | 30,242,201 | |
| -1 | -30,242,201 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 30,242,201.
Example:
1 x 30,242,201 = 30,242,201
and
-1 x -30,242,201 = 30,242,201
Notice both answers equal 30,242,201
With that explanation out of the way, let's continue. Next, we take the number 30,242,201 and divide it by 2:
30,242,201 ÷ 2 = 15,121,100.5
If the quotient is a whole number, then 2 and 15,121,100.5 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 | 30,242,201 | |
| -1 | -30,242,201 |
Now, we try dividing 30,242,201 by 3:
30,242,201 ÷ 3 = 10,080,733.6667
If the quotient is a whole number, then 3 and 10,080,733.6667 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 | 30,242,201 | |
| -1 | -30,242,201 |
Let's try dividing by 4:
30,242,201 ÷ 4 = 7,560,550.25
If the quotient is a whole number, then 4 and 7,560,550.25 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 | 30,242,201 | |
| -1 | 30,242,201 |
If you did it right, you will end up with this table:
| 1 | 11 | 17 | 43 | 187 | 473 | 731 | 3,761 | 8,041 | 41,371 | 63,937 | 161,723 | 703,307 | 1,778,953 | 2,749,291 | 30,242,201 |
| -1 | -11 | -17 | -43 | -187 | -473 | -731 | -3,761 | -8,041 | -41,371 | -63,937 | -161,723 | -703,307 | -1,778,953 | -2,749,291 | -30,242,201 |
