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 5,310,823, 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 | 5,310,823 | |
| -1 | -5,310,823 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 5,310,823.
Example:
1 x 5,310,823 = 5,310,823
and
-1 x -5,310,823 = 5,310,823
Notice both answers equal 5,310,823
With that explanation out of the way, let's continue. Next, we take the number 5,310,823 and divide it by 2:
5,310,823 ÷ 2 = 2,655,411.5
If the quotient is a whole number, then 2 and 2,655,411.5 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 | 5,310,823 | |
| -1 | -5,310,823 |
Now, we try dividing 5,310,823 by 3:
5,310,823 ÷ 3 = 1,770,274.3333
If the quotient is a whole number, then 3 and 1,770,274.3333 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 | 5,310,823 | |
| -1 | -5,310,823 |
Let's try dividing by 4:
5,310,823 ÷ 4 = 1,327,705.75
If the quotient is a whole number, then 4 and 1,327,705.75 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 | 5,310,823 | |
| -1 | 5,310,823 |
If you did it right, you will end up with this table:
| 1 | 7 | 19 | 73 | 133 | 511 | 547 | 1,387 | 3,829 | 9,709 | 10,393 | 39,931 | 72,751 | 279,517 | 758,689 | 5,310,823 |
| -1 | -7 | -19 | -73 | -133 | -511 | -547 | -1,387 | -3,829 | -9,709 | -10,393 | -39,931 | -72,751 | -279,517 | -758,689 | -5,310,823 |
