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 6,560,225, 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 | 6,560,225 | |
| -1 | -6,560,225 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 6,560,225.
Example:
1 x 6,560,225 = 6,560,225
and
-1 x -6,560,225 = 6,560,225
Notice both answers equal 6,560,225
With that explanation out of the way, let's continue. Next, we take the number 6,560,225 and divide it by 2:
6,560,225 ÷ 2 = 3,280,112.5
If the quotient is a whole number, then 2 and 3,280,112.5 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 | 6,560,225 | |
| -1 | -6,560,225 |
Now, we try dividing 6,560,225 by 3:
6,560,225 ÷ 3 = 2,186,741.6667
If the quotient is a whole number, then 3 and 2,186,741.6667 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 | 6,560,225 | |
| -1 | -6,560,225 |
Let's try dividing by 4:
6,560,225 ÷ 4 = 1,640,056.25
If the quotient is a whole number, then 4 and 1,640,056.25 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 | 6,560,225 | |
| -1 | 6,560,225 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 19 | 25 | 35 | 95 | 133 | 175 | 475 | 665 | 1,973 | 3,325 | 9,865 | 13,811 | 37,487 | 49,325 | 69,055 | 187,435 | 262,409 | 345,275 | 937,175 | 1,312,045 | 6,560,225 |
| -1 | -5 | -7 | -19 | -25 | -35 | -95 | -133 | -175 | -475 | -665 | -1,973 | -3,325 | -9,865 | -13,811 | -37,487 | -49,325 | -69,055 | -187,435 | -262,409 | -345,275 | -937,175 | -1,312,045 | -6,560,225 |
