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 5,230,445, 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 | 5,230,445 | |
| -1 | -5,230,445 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 5,230,445.
Example:
1 x 5,230,445 = 5,230,445
and
-1 x -5,230,445 = 5,230,445
Notice both answers equal 5,230,445
With that explanation out of the way, let's continue. Next, we take the number 5,230,445 and divide it by 2:
5,230,445 ÷ 2 = 2,615,222.5
If the quotient is a whole number, then 2 and 2,615,222.5 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 | 5,230,445 | |
| -1 | -5,230,445 |
Now, we try dividing 5,230,445 by 3:
5,230,445 ÷ 3 = 1,743,481.6667
If the quotient is a whole number, then 3 and 1,743,481.6667 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 | 5,230,445 | |
| -1 | -5,230,445 |
Let's try dividing by 4:
5,230,445 ÷ 4 = 1,307,611.25
If the quotient is a whole number, then 4 and 1,307,611.25 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 | 5,230,445 | |
| -1 | 5,230,445 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 61 | 305 | 671 | 1,559 | 3,355 | 7,795 | 17,149 | 85,745 | 95,099 | 475,495 | 1,046,089 | 5,230,445 |
| -1 | -5 | -11 | -55 | -61 | -305 | -671 | -1,559 | -3,355 | -7,795 | -17,149 | -85,745 | -95,099 | -475,495 | -1,046,089 | -5,230,445 |
