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 5,291,891, 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 | 5,291,891 | |
| -1 | -5,291,891 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 5,291,891.
Example:
1 x 5,291,891 = 5,291,891
and
-1 x -5,291,891 = 5,291,891
Notice both answers equal 5,291,891
With that explanation out of the way, let's continue. Next, we take the number 5,291,891 and divide it by 2:
5,291,891 ÷ 2 = 2,645,945.5
If the quotient is a whole number, then 2 and 2,645,945.5 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 | 5,291,891 | |
| -1 | -5,291,891 |
Now, we try dividing 5,291,891 by 3:
5,291,891 ÷ 3 = 1,763,963.6667
If the quotient is a whole number, then 3 and 1,763,963.6667 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 | 5,291,891 | |
| -1 | -5,291,891 |
Let's try dividing by 4:
5,291,891 ÷ 4 = 1,322,972.75
If the quotient is a whole number, then 4 and 1,322,972.75 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 | 5,291,891 | |
| -1 | 5,291,891 |
If you did it right, you will end up with this table:
| 1 | 11 | 29 | 53 | 313 | 319 | 583 | 1,537 | 3,443 | 9,077 | 16,589 | 16,907 | 99,847 | 182,479 | 481,081 | 5,291,891 |
| -1 | -11 | -29 | -53 | -313 | -319 | -583 | -1,537 | -3,443 | -9,077 | -16,589 | -16,907 | -99,847 | -182,479 | -481,081 | -5,291,891 |
