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 5,312,645, 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 | 5,312,645 | |
| -1 | -5,312,645 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 5,312,645.
Example:
1 x 5,312,645 = 5,312,645
and
-1 x -5,312,645 = 5,312,645
Notice both answers equal 5,312,645
With that explanation out of the way, let's continue. Next, we take the number 5,312,645 and divide it by 2:
5,312,645 ÷ 2 = 2,656,322.5
If the quotient is a whole number, then 2 and 2,656,322.5 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 | 5,312,645 | |
| -1 | -5,312,645 |
Now, we try dividing 5,312,645 by 3:
5,312,645 ÷ 3 = 1,770,881.6667
If the quotient is a whole number, then 3 and 1,770,881.6667 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 | 5,312,645 | |
| -1 | -5,312,645 |
Let's try dividing by 4:
5,312,645 ÷ 4 = 1,328,161.25
If the quotient is a whole number, then 4 and 1,328,161.25 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 | 5,312,645 | |
| -1 | 5,312,645 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 37 | 47 | 65 | 185 | 235 | 481 | 611 | 1,739 | 2,209 | 2,405 | 3,055 | 8,695 | 11,045 | 22,607 | 28,717 | 81,733 | 113,035 | 143,585 | 408,665 | 1,062,529 | 5,312,645 |
| -1 | -5 | -13 | -37 | -47 | -65 | -185 | -235 | -481 | -611 | -1,739 | -2,209 | -2,405 | -3,055 | -8,695 | -11,045 | -22,607 | -28,717 | -81,733 | -113,035 | -143,585 | -408,665 | -1,062,529 | -5,312,645 |
