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 5,131,273, 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 | 5,131,273 | |
| -1 | -5,131,273 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 5,131,273.
Example:
1 x 5,131,273 = 5,131,273
and
-1 x -5,131,273 = 5,131,273
Notice both answers equal 5,131,273
With that explanation out of the way, let's continue. Next, we take the number 5,131,273 and divide it by 2:
5,131,273 ÷ 2 = 2,565,636.5
If the quotient is a whole number, then 2 and 2,565,636.5 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 | 5,131,273 | |
| -1 | -5,131,273 |
Now, we try dividing 5,131,273 by 3:
5,131,273 ÷ 3 = 1,710,424.3333
If the quotient is a whole number, then 3 and 1,710,424.3333 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 | 5,131,273 | |
| -1 | -5,131,273 |
Let's try dividing by 4:
5,131,273 ÷ 4 = 1,282,818.25
If the quotient is a whole number, then 4 and 1,282,818.25 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 | 5,131,273 | |
| -1 | 5,131,273 |
If you did it right, you will end up with this table:
| 1 | 7 | 19 | 41 | 133 | 287 | 779 | 941 | 5,453 | 6,587 | 17,879 | 38,581 | 125,153 | 270,067 | 733,039 | 5,131,273 |
| -1 | -7 | -19 | -41 | -133 | -287 | -779 | -941 | -5,453 | -6,587 | -17,879 | -38,581 | -125,153 | -270,067 | -733,039 | -5,131,273 |
