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 7,625,375, 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 | 7,625,375 | |
| -1 | -7,625,375 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 7,625,375.
Example:
1 x 7,625,375 = 7,625,375
and
-1 x -7,625,375 = 7,625,375
Notice both answers equal 7,625,375
With that explanation out of the way, let's continue. Next, we take the number 7,625,375 and divide it by 2:
7,625,375 ÷ 2 = 3,812,687.5
If the quotient is a whole number, then 2 and 3,812,687.5 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 | 7,625,375 | |
| -1 | -7,625,375 |
Now, we try dividing 7,625,375 by 3:
7,625,375 ÷ 3 = 2,541,791.6667
If the quotient is a whole number, then 3 and 2,541,791.6667 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 | 7,625,375 | |
| -1 | -7,625,375 |
Let's try dividing by 4:
7,625,375 ÷ 4 = 1,906,343.75
If the quotient is a whole number, then 4 and 1,906,343.75 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 | 7,625,375 | |
| -1 | 7,625,375 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 53 | 125 | 265 | 1,151 | 1,325 | 5,755 | 6,625 | 28,775 | 61,003 | 143,875 | 305,015 | 1,525,075 | 7,625,375 |
| -1 | -5 | -25 | -53 | -125 | -265 | -1,151 | -1,325 | -5,755 | -6,625 | -28,775 | -61,003 | -143,875 | -305,015 | -1,525,075 | -7,625,375 |
