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 738,211,793, 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 | 738,211,793 | |
| -1 | -738,211,793 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 738,211,793.
Example:
1 x 738,211,793 = 738,211,793
and
-1 x -738,211,793 = 738,211,793
Notice both answers equal 738,211,793
With that explanation out of the way, let's continue. Next, we take the number 738,211,793 and divide it by 2:
738,211,793 ÷ 2 = 369,105,896.5
If the quotient is a whole number, then 2 and 369,105,896.5 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 | 738,211,793 | |
| -1 | -738,211,793 |
Now, we try dividing 738,211,793 by 3:
738,211,793 ÷ 3 = 246,070,597.6667
If the quotient is a whole number, then 3 and 246,070,597.6667 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 | 738,211,793 | |
| -1 | -738,211,793 |
Let's try dividing by 4:
738,211,793 ÷ 4 = 184,552,948.25
If the quotient is a whole number, then 4 and 184,552,948.25 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 | 738,211,793 | |
| -1 | 738,211,793 |
If you did it right, you will end up with this table:
| 1 | 11 | 199 | 563 | 599 | 2,189 | 6,193 | 6,589 | 112,037 | 119,201 | 337,237 | 1,232,407 | 1,311,211 | 3,709,607 | 67,110,163 | 738,211,793 |
| -1 | -11 | -199 | -563 | -599 | -2,189 | -6,193 | -6,589 | -112,037 | -119,201 | -337,237 | -1,232,407 | -1,311,211 | -3,709,607 | -67,110,163 | -738,211,793 |
