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 5,120,225, 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 | 5,120,225 | |
| -1 | -5,120,225 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 5,120,225.
Example:
1 x 5,120,225 = 5,120,225
and
-1 x -5,120,225 = 5,120,225
Notice both answers equal 5,120,225
With that explanation out of the way, let's continue. Next, we take the number 5,120,225 and divide it by 2:
5,120,225 ÷ 2 = 2,560,112.5
If the quotient is a whole number, then 2 and 2,560,112.5 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 | 5,120,225 | |
| -1 | -5,120,225 |
Now, we try dividing 5,120,225 by 3:
5,120,225 ÷ 3 = 1,706,741.6667
If the quotient is a whole number, then 3 and 1,706,741.6667 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 | 5,120,225 | |
| -1 | -5,120,225 |
Let's try dividing by 4:
5,120,225 ÷ 4 = 1,280,056.25
If the quotient is a whole number, then 4 and 1,280,056.25 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 | 5,120,225 | |
| -1 | 5,120,225 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 25 | 43 | 55 | 215 | 275 | 433 | 473 | 1,075 | 2,165 | 2,365 | 4,763 | 10,825 | 11,825 | 18,619 | 23,815 | 93,095 | 119,075 | 204,809 | 465,475 | 1,024,045 | 5,120,225 |
| -1 | -5 | -11 | -25 | -43 | -55 | -215 | -275 | -433 | -473 | -1,075 | -2,165 | -2,365 | -4,763 | -10,825 | -11,825 | -18,619 | -23,815 | -93,095 | -119,075 | -204,809 | -465,475 | -1,024,045 | -5,120,225 |
