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 738,286,735, 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 | 738,286,735 | |
| -1 | -738,286,735 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 738,286,735.
Example:
1 x 738,286,735 = 738,286,735
and
-1 x -738,286,735 = 738,286,735
Notice both answers equal 738,286,735
With that explanation out of the way, let's continue. Next, we take the number 738,286,735 and divide it by 2:
738,286,735 ÷ 2 = 369,143,367.5
If the quotient is a whole number, then 2 and 369,143,367.5 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 | 738,286,735 | |
| -1 | -738,286,735 |
Now, we try dividing 738,286,735 by 3:
738,286,735 ÷ 3 = 246,095,578.3333
If the quotient is a whole number, then 3 and 246,095,578.3333 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 | 738,286,735 | |
| -1 | -738,286,735 |
Let's try dividing by 4:
738,286,735 ÷ 4 = 184,571,683.75
If the quotient is a whole number, then 4 and 184,571,683.75 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 | 738,286,735 | |
| -1 | 738,286,735 |
If you did it right, you will end up with this table:
| 1 | 5 | 67 | 335 | 1,117 | 1,973 | 5,585 | 9,865 | 74,839 | 132,191 | 374,195 | 660,955 | 2,203,841 | 11,019,205 | 147,657,347 | 738,286,735 |
| -1 | -5 | -67 | -335 | -1,117 | -1,973 | -5,585 | -9,865 | -74,839 | -132,191 | -374,195 | -660,955 | -2,203,841 | -11,019,205 | -147,657,347 | -738,286,735 |
