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 7,535,215, 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 | 7,535,215 | |
| -1 | -7,535,215 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 7,535,215.
Example:
1 x 7,535,215 = 7,535,215
and
-1 x -7,535,215 = 7,535,215
Notice both answers equal 7,535,215
With that explanation out of the way, let's continue. Next, we take the number 7,535,215 and divide it by 2:
7,535,215 ÷ 2 = 3,767,607.5
If the quotient is a whole number, then 2 and 3,767,607.5 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 | 7,535,215 | |
| -1 | -7,535,215 |
Now, we try dividing 7,535,215 by 3:
7,535,215 ÷ 3 = 2,511,738.3333
If the quotient is a whole number, then 3 and 2,511,738.3333 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 | 7,535,215 | |
| -1 | -7,535,215 |
Let's try dividing by 4:
7,535,215 ÷ 4 = 1,883,803.75
If the quotient is a whole number, then 4 and 1,883,803.75 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 | 7,535,215 | |
| -1 | 7,535,215 |
If you did it right, you will end up with this table:
| 1 | 5 | 29 | 145 | 157 | 331 | 785 | 1,655 | 4,553 | 9,599 | 22,765 | 47,995 | 51,967 | 259,835 | 1,507,043 | 7,535,215 |
| -1 | -5 | -29 | -145 | -157 | -331 | -785 | -1,655 | -4,553 | -9,599 | -22,765 | -47,995 | -51,967 | -259,835 | -1,507,043 | -7,535,215 |
