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 7,531,825, 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 | 7,531,825 | |
| -1 | -7,531,825 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 7,531,825.
Example:
1 x 7,531,825 = 7,531,825
and
-1 x -7,531,825 = 7,531,825
Notice both answers equal 7,531,825
With that explanation out of the way, let's continue. Next, we take the number 7,531,825 and divide it by 2:
7,531,825 ÷ 2 = 3,765,912.5
If the quotient is a whole number, then 2 and 3,765,912.5 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 | 7,531,825 | |
| -1 | -7,531,825 |
Now, we try dividing 7,531,825 by 3:
7,531,825 ÷ 3 = 2,510,608.3333
If the quotient is a whole number, then 3 and 2,510,608.3333 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 | 7,531,825 | |
| -1 | -7,531,825 |
Let's try dividing by 4:
7,531,825 ÷ 4 = 1,882,956.25
If the quotient is a whole number, then 4 and 1,882,956.25 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 | 7,531,825 | |
| -1 | 7,531,825 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 25 | 35 | 175 | 193 | 223 | 965 | 1,115 | 1,351 | 1,561 | 4,825 | 5,575 | 6,755 | 7,805 | 33,775 | 39,025 | 43,039 | 215,195 | 301,273 | 1,075,975 | 1,506,365 | 7,531,825 |
| -1 | -5 | -7 | -25 | -35 | -175 | -193 | -223 | -965 | -1,115 | -1,351 | -1,561 | -4,825 | -5,575 | -6,755 | -7,805 | -33,775 | -39,025 | -43,039 | -215,195 | -301,273 | -1,075,975 | -1,506,365 | -7,531,825 |
