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 7,863,713, 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 | 7,863,713 | |
| -1 | -7,863,713 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 7,863,713.
Example:
1 x 7,863,713 = 7,863,713
and
-1 x -7,863,713 = 7,863,713
Notice both answers equal 7,863,713
With that explanation out of the way, let's continue. Next, we take the number 7,863,713 and divide it by 2:
7,863,713 ÷ 2 = 3,931,856.5
If the quotient is a whole number, then 2 and 3,931,856.5 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 | 7,863,713 | |
| -1 | -7,863,713 |
Now, we try dividing 7,863,713 by 3:
7,863,713 ÷ 3 = 2,621,237.6667
If the quotient is a whole number, then 3 and 2,621,237.6667 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 | 7,863,713 | |
| -1 | -7,863,713 |
Let's try dividing by 4:
7,863,713 ÷ 4 = 1,965,928.25
If the quotient is a whole number, then 4 and 1,965,928.25 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 | 7,863,713 | |
| -1 | 7,863,713 |
If you did it right, you will end up with this table:
| 1 | 11 | 13 | 127 | 143 | 433 | 1,397 | 1,651 | 4,763 | 5,629 | 18,161 | 54,991 | 61,919 | 604,901 | 714,883 | 7,863,713 |
| -1 | -11 | -13 | -127 | -143 | -433 | -1,397 | -1,651 | -4,763 | -5,629 | -18,161 | -54,991 | -61,919 | -604,901 | -714,883 | -7,863,713 |
