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 500,303,237, 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 | 500,303,237 | |
| -1 | -500,303,237 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 500,303,237.
Example:
1 x 500,303,237 = 500,303,237
and
-1 x -500,303,237 = 500,303,237
Notice both answers equal 500,303,237
With that explanation out of the way, let's continue. Next, we take the number 500,303,237 and divide it by 2:
500,303,237 ÷ 2 = 250,151,618.5
If the quotient is a whole number, then 2 and 250,151,618.5 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 | 500,303,237 | |
| -1 | -500,303,237 |
Now, we try dividing 500,303,237 by 3:
500,303,237 ÷ 3 = 166,767,745.6667
If the quotient is a whole number, then 3 and 166,767,745.6667 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 | 500,303,237 | |
| -1 | -500,303,237 |
Let's try dividing by 4:
500,303,237 ÷ 4 = 125,075,809.25
If the quotient is a whole number, then 4 and 125,075,809.25 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 | 500,303,237 | |
| -1 | 500,303,237 |
If you did it right, you will end up with this table:
| 1 | 7 | 43 | 73 | 301 | 511 | 3,139 | 21,973 | 22,769 | 159,383 | 979,067 | 1,662,137 | 6,853,469 | 11,634,959 | 71,471,891 | 500,303,237 |
| -1 | -7 | -43 | -73 | -301 | -511 | -3,139 | -21,973 | -22,769 | -159,383 | -979,067 | -1,662,137 | -6,853,469 | -11,634,959 | -71,471,891 | -500,303,237 |
