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 733,137,143, 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 | 733,137,143 | |
| -1 | -733,137,143 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 733,137,143.
Example:
1 x 733,137,143 = 733,137,143
and
-1 x -733,137,143 = 733,137,143
Notice both answers equal 733,137,143
With that explanation out of the way, let's continue. Next, we take the number 733,137,143 and divide it by 2:
733,137,143 ÷ 2 = 366,568,571.5
If the quotient is a whole number, then 2 and 366,568,571.5 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 | 733,137,143 | |
| -1 | -733,137,143 |
Now, we try dividing 733,137,143 by 3:
733,137,143 ÷ 3 = 244,379,047.6667
If the quotient is a whole number, then 3 and 244,379,047.6667 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 | 733,137,143 | |
| -1 | -733,137,143 |
Let's try dividing by 4:
733,137,143 ÷ 4 = 183,284,285.75
If the quotient is a whole number, then 4 and 183,284,285.75 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 | 733,137,143 | |
| -1 | 733,137,143 |
If you did it right, you will end up with this table:
| 1 | 43 | 79 | 107 | 2,017 | 3,397 | 4,601 | 8,453 | 86,731 | 159,343 | 215,819 | 363,479 | 6,851,749 | 9,280,217 | 17,049,701 | 733,137,143 |
| -1 | -43 | -79 | -107 | -2,017 | -3,397 | -4,601 | -8,453 | -86,731 | -159,343 | -215,819 | -363,479 | -6,851,749 | -9,280,217 | -17,049,701 | -733,137,143 |
