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 30,073,555, 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 | 30,073,555 | |
| -1 | -30,073,555 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 30,073,555.
Example:
1 x 30,073,555 = 30,073,555
and
-1 x -30,073,555 = 30,073,555
Notice both answers equal 30,073,555
With that explanation out of the way, let's continue. Next, we take the number 30,073,555 and divide it by 2:
30,073,555 ÷ 2 = 15,036,777.5
If the quotient is a whole number, then 2 and 15,036,777.5 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 | 30,073,555 | |
| -1 | -30,073,555 |
Now, we try dividing 30,073,555 by 3:
30,073,555 ÷ 3 = 10,024,518.3333
If the quotient is a whole number, then 3 and 10,024,518.3333 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 | 30,073,555 | |
| -1 | -30,073,555 |
Let's try dividing by 4:
30,073,555 ÷ 4 = 7,518,388.75
If the quotient is a whole number, then 4 and 7,518,388.75 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 | 30,073,555 | |
| -1 | 30,073,555 |
If you did it right, you will end up with this table:
| 1 | 5 | 43 | 137 | 215 | 685 | 1,021 | 5,105 | 5,891 | 29,455 | 43,903 | 139,877 | 219,515 | 699,385 | 6,014,711 | 30,073,555 |
| -1 | -5 | -43 | -137 | -215 | -685 | -1,021 | -5,105 | -5,891 | -29,455 | -43,903 | -139,877 | -219,515 | -699,385 | -6,014,711 | -30,073,555 |
