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 30,223,195, 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 | 30,223,195 | |
| -1 | -30,223,195 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 30,223,195.
Example:
1 x 30,223,195 = 30,223,195
and
-1 x -30,223,195 = 30,223,195
Notice both answers equal 30,223,195
With that explanation out of the way, let's continue. Next, we take the number 30,223,195 and divide it by 2:
30,223,195 ÷ 2 = 15,111,597.5
If the quotient is a whole number, then 2 and 15,111,597.5 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 | 30,223,195 | |
| -1 | -30,223,195 |
Now, we try dividing 30,223,195 by 3:
30,223,195 ÷ 3 = 10,074,398.3333
If the quotient is a whole number, then 3 and 10,074,398.3333 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 | 30,223,195 | |
| -1 | -30,223,195 |
Let's try dividing by 4:
30,223,195 ÷ 4 = 7,555,798.75
If the quotient is a whole number, then 4 and 7,555,798.75 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 | 30,223,195 | |
| -1 | 30,223,195 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 43 | 85 | 215 | 731 | 3,655 | 8,269 | 41,345 | 140,573 | 355,567 | 702,865 | 1,777,835 | 6,044,639 | 30,223,195 |
| -1 | -5 | -17 | -43 | -85 | -215 | -731 | -3,655 | -8,269 | -41,345 | -140,573 | -355,567 | -702,865 | -1,777,835 | -6,044,639 | -30,223,195 |
