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 5,045,821, 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 | 5,045,821 | |
| -1 | -5,045,821 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 5,045,821.
Example:
1 x 5,045,821 = 5,045,821
and
-1 x -5,045,821 = 5,045,821
Notice both answers equal 5,045,821
With that explanation out of the way, let's continue. Next, we take the number 5,045,821 and divide it by 2:
5,045,821 ÷ 2 = 2,522,910.5
If the quotient is a whole number, then 2 and 2,522,910.5 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 | 5,045,821 | |
| -1 | -5,045,821 |
Now, we try dividing 5,045,821 by 3:
5,045,821 ÷ 3 = 1,681,940.3333
If the quotient is a whole number, then 3 and 1,681,940.3333 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 | 5,045,821 | |
| -1 | -5,045,821 |
Let's try dividing by 4:
5,045,821 ÷ 4 = 1,261,455.25
If the quotient is a whole number, then 4 and 1,261,455.25 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 | 5,045,821 | |
| -1 | 5,045,821 |
If you did it right, you will end up with this table:
| 1 | 11 | 17 | 121 | 187 | 223 | 1,331 | 2,057 | 2,453 | 3,791 | 22,627 | 26,983 | 41,701 | 296,813 | 458,711 | 5,045,821 |
| -1 | -11 | -17 | -121 | -187 | -223 | -1,331 | -2,057 | -2,453 | -3,791 | -22,627 | -26,983 | -41,701 | -296,813 | -458,711 | -5,045,821 |
