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 7,528,375, 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 | 7,528,375 | |
| -1 | -7,528,375 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 7,528,375.
Example:
1 x 7,528,375 = 7,528,375
and
-1 x -7,528,375 = 7,528,375
Notice both answers equal 7,528,375
With that explanation out of the way, let's continue. Next, we take the number 7,528,375 and divide it by 2:
7,528,375 ÷ 2 = 3,764,187.5
If the quotient is a whole number, then 2 and 3,764,187.5 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 | 7,528,375 | |
| -1 | -7,528,375 |
Now, we try dividing 7,528,375 by 3:
7,528,375 ÷ 3 = 2,509,458.3333
If the quotient is a whole number, then 3 and 2,509,458.3333 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 | 7,528,375 | |
| -1 | -7,528,375 |
Let's try dividing by 4:
7,528,375 ÷ 4 = 1,882,093.75
If the quotient is a whole number, then 4 and 1,882,093.75 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 | 7,528,375 | |
| -1 | 7,528,375 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 125 | 229 | 263 | 1,145 | 1,315 | 5,725 | 6,575 | 28,625 | 32,875 | 60,227 | 301,135 | 1,505,675 | 7,528,375 |
| -1 | -5 | -25 | -125 | -229 | -263 | -1,145 | -1,315 | -5,725 | -6,575 | -28,625 | -32,875 | -60,227 | -301,135 | -1,505,675 | -7,528,375 |
