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 738,338,065, 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 | 738,338,065 | |
| -1 | -738,338,065 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 738,338,065.
Example:
1 x 738,338,065 = 738,338,065
and
-1 x -738,338,065 = 738,338,065
Notice both answers equal 738,338,065
With that explanation out of the way, let's continue. Next, we take the number 738,338,065 and divide it by 2:
738,338,065 ÷ 2 = 369,169,032.5
If the quotient is a whole number, then 2 and 369,169,032.5 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 | 738,338,065 | |
| -1 | -738,338,065 |
Now, we try dividing 738,338,065 by 3:
738,338,065 ÷ 3 = 246,112,688.3333
If the quotient is a whole number, then 3 and 246,112,688.3333 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 | 738,338,065 | |
| -1 | -738,338,065 |
Let's try dividing by 4:
738,338,065 ÷ 4 = 184,584,516.25
If the quotient is a whole number, then 4 and 184,584,516.25 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 | 738,338,065 | |
| -1 | 738,338,065 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 115 | 2,161 | 2,971 | 10,805 | 14,855 | 49,703 | 68,333 | 248,515 | 341,665 | 6,420,331 | 32,101,655 | 147,667,613 | 738,338,065 |
| -1 | -5 | -23 | -115 | -2,161 | -2,971 | -10,805 | -14,855 | -49,703 | -68,333 | -248,515 | -341,665 | -6,420,331 | -32,101,655 | -147,667,613 | -738,338,065 |
