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 5,117,431, 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 | 5,117,431 | |
| -1 | -5,117,431 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 5,117,431.
Example:
1 x 5,117,431 = 5,117,431
and
-1 x -5,117,431 = 5,117,431
Notice both answers equal 5,117,431
With that explanation out of the way, let's continue. Next, we take the number 5,117,431 and divide it by 2:
5,117,431 ÷ 2 = 2,558,715.5
If the quotient is a whole number, then 2 and 2,558,715.5 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 | 5,117,431 | |
| -1 | -5,117,431 |
Now, we try dividing 5,117,431 by 3:
5,117,431 ÷ 3 = 1,705,810.3333
If the quotient is a whole number, then 3 and 1,705,810.3333 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 | 5,117,431 | |
| -1 | -5,117,431 |
Let's try dividing by 4:
5,117,431 ÷ 4 = 1,279,357.75
If the quotient is a whole number, then 4 and 1,279,357.75 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 | 5,117,431 | |
| -1 | 5,117,431 |
If you did it right, you will end up with this table:
| 1 | 11 | 23 | 113 | 179 | 253 | 1,243 | 1,969 | 2,599 | 4,117 | 20,227 | 28,589 | 45,287 | 222,497 | 465,221 | 5,117,431 |
| -1 | -11 | -23 | -113 | -179 | -253 | -1,243 | -1,969 | -2,599 | -4,117 | -20,227 | -28,589 | -45,287 | -222,497 | -465,221 | -5,117,431 |
