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 5,181,847, 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 | 5,181,847 | |
| -1 | -5,181,847 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 5,181,847.
Example:
1 x 5,181,847 = 5,181,847
and
-1 x -5,181,847 = 5,181,847
Notice both answers equal 5,181,847
With that explanation out of the way, let's continue. Next, we take the number 5,181,847 and divide it by 2:
5,181,847 ÷ 2 = 2,590,923.5
If the quotient is a whole number, then 2 and 2,590,923.5 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 | 5,181,847 | |
| -1 | -5,181,847 |
Now, we try dividing 5,181,847 by 3:
5,181,847 ÷ 3 = 1,727,282.3333
If the quotient is a whole number, then 3 and 1,727,282.3333 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 | 5,181,847 | |
| -1 | -5,181,847 |
Let's try dividing by 4:
5,181,847 ÷ 4 = 1,295,461.75
If the quotient is a whole number, then 4 and 1,295,461.75 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 | 5,181,847 | |
| -1 | 5,181,847 |
If you did it right, you will end up with this table:
| 1 | 11 | 67 | 79 | 89 | 737 | 869 | 979 | 5,293 | 5,963 | 7,031 | 58,223 | 65,593 | 77,341 | 471,077 | 5,181,847 |
| -1 | -11 | -67 | -79 | -89 | -737 | -869 | -979 | -5,293 | -5,963 | -7,031 | -58,223 | -65,593 | -77,341 | -471,077 | -5,181,847 |
