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 6,530,225, 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 | 6,530,225 | |
| -1 | -6,530,225 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 6,530,225.
Example:
1 x 6,530,225 = 6,530,225
and
-1 x -6,530,225 = 6,530,225
Notice both answers equal 6,530,225
With that explanation out of the way, let's continue. Next, we take the number 6,530,225 and divide it by 2:
6,530,225 ÷ 2 = 3,265,112.5
If the quotient is a whole number, then 2 and 3,265,112.5 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 | 6,530,225 | |
| -1 | -6,530,225 |
Now, we try dividing 6,530,225 by 3:
6,530,225 ÷ 3 = 2,176,741.6667
If the quotient is a whole number, then 3 and 2,176,741.6667 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 | 6,530,225 | |
| -1 | -6,530,225 |
Let's try dividing by 4:
6,530,225 ÷ 4 = 1,632,556.25
If the quotient is a whole number, then 4 and 1,632,556.25 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 | 6,530,225 | |
| -1 | 6,530,225 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 25 | 65 | 71 | 283 | 325 | 355 | 923 | 1,415 | 1,775 | 3,679 | 4,615 | 7,075 | 18,395 | 20,093 | 23,075 | 91,975 | 100,465 | 261,209 | 502,325 | 1,306,045 | 6,530,225 |
| -1 | -5 | -13 | -25 | -65 | -71 | -283 | -325 | -355 | -923 | -1,415 | -1,775 | -3,679 | -4,615 | -7,075 | -18,395 | -20,093 | -23,075 | -91,975 | -100,465 | -261,209 | -502,325 | -1,306,045 | -6,530,225 |
