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 6,315,625, 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 | 6,315,625 | |
| -1 | -6,315,625 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 6,315,625.
Example:
1 x 6,315,625 = 6,315,625
and
-1 x -6,315,625 = 6,315,625
Notice both answers equal 6,315,625
With that explanation out of the way, let's continue. Next, we take the number 6,315,625 and divide it by 2:
6,315,625 ÷ 2 = 3,157,812.5
If the quotient is a whole number, then 2 and 3,157,812.5 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 | 6,315,625 | |
| -1 | -6,315,625 |
Now, we try dividing 6,315,625 by 3:
6,315,625 ÷ 3 = 2,105,208.3333
If the quotient is a whole number, then 3 and 2,105,208.3333 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 | 6,315,625 | |
| -1 | -6,315,625 |
Let's try dividing by 4:
6,315,625 ÷ 4 = 1,578,906.25
If the quotient is a whole number, then 4 and 1,578,906.25 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 | 6,315,625 | |
| -1 | 6,315,625 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 43 | 47 | 125 | 215 | 235 | 625 | 1,075 | 1,175 | 2,021 | 3,125 | 5,375 | 5,875 | 10,105 | 26,875 | 29,375 | 50,525 | 134,375 | 146,875 | 252,625 | 1,263,125 | 6,315,625 |
| -1 | -5 | -25 | -43 | -47 | -125 | -215 | -235 | -625 | -1,075 | -1,175 | -2,021 | -3,125 | -5,375 | -5,875 | -10,105 | -26,875 | -29,375 | -50,525 | -134,375 | -146,875 | -252,625 | -1,263,125 | -6,315,625 |
