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 30,268,075, 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 | 30,268,075 | |
| -1 | -30,268,075 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 30,268,075.
Example:
1 x 30,268,075 = 30,268,075
and
-1 x -30,268,075 = 30,268,075
Notice both answers equal 30,268,075
With that explanation out of the way, let's continue. Next, we take the number 30,268,075 and divide it by 2:
30,268,075 ÷ 2 = 15,134,037.5
If the quotient is a whole number, then 2 and 15,134,037.5 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 | 30,268,075 | |
| -1 | -30,268,075 |
Now, we try dividing 30,268,075 by 3:
30,268,075 ÷ 3 = 10,089,358.3333
If the quotient is a whole number, then 3 and 10,089,358.3333 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 | 30,268,075 | |
| -1 | -30,268,075 |
Let's try dividing by 4:
30,268,075 ÷ 4 = 7,567,018.75
If the quotient is a whole number, then 4 and 7,567,018.75 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 | 30,268,075 | |
| -1 | 30,268,075 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 25 | 85 | 229 | 311 | 425 | 1,145 | 1,555 | 3,893 | 5,287 | 5,725 | 7,775 | 19,465 | 26,435 | 71,219 | 97,325 | 132,175 | 356,095 | 1,210,723 | 1,780,475 | 6,053,615 | 30,268,075 |
| -1 | -5 | -17 | -25 | -85 | -229 | -311 | -425 | -1,145 | -1,555 | -3,893 | -5,287 | -5,725 | -7,775 | -19,465 | -26,435 | -71,219 | -97,325 | -132,175 | -356,095 | -1,210,723 | -1,780,475 | -6,053,615 | -30,268,075 |
