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 30,110,245, 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 | 30,110,245 | |
| -1 | -30,110,245 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 30,110,245.
Example:
1 x 30,110,245 = 30,110,245
and
-1 x -30,110,245 = 30,110,245
Notice both answers equal 30,110,245
With that explanation out of the way, let's continue. Next, we take the number 30,110,245 and divide it by 2:
30,110,245 ÷ 2 = 15,055,122.5
If the quotient is a whole number, then 2 and 15,055,122.5 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 | 30,110,245 | |
| -1 | -30,110,245 |
Now, we try dividing 30,110,245 by 3:
30,110,245 ÷ 3 = 10,036,748.3333
If the quotient is a whole number, then 3 and 10,036,748.3333 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 | 30,110,245 | |
| -1 | -30,110,245 |
Let's try dividing by 4:
30,110,245 ÷ 4 = 7,527,561.25
If the quotient is a whole number, then 4 and 7,527,561.25 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 | 30,110,245 | |
| -1 | 30,110,245 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 121 | 157 | 317 | 605 | 785 | 1,585 | 1,727 | 3,487 | 8,635 | 17,435 | 18,997 | 38,357 | 49,769 | 94,985 | 191,785 | 248,845 | 547,459 | 2,737,295 | 6,022,049 | 30,110,245 |
| -1 | -5 | -11 | -55 | -121 | -157 | -317 | -605 | -785 | -1,585 | -1,727 | -3,487 | -8,635 | -17,435 | -18,997 | -38,357 | -49,769 | -94,985 | -191,785 | -248,845 | -547,459 | -2,737,295 | -6,022,049 | -30,110,245 |
