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 500,216,645, 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 | 500,216,645 | |
| -1 | -500,216,645 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 500,216,645.
Example:
1 x 500,216,645 = 500,216,645
and
-1 x -500,216,645 = 500,216,645
Notice both answers equal 500,216,645
With that explanation out of the way, let's continue. Next, we take the number 500,216,645 and divide it by 2:
500,216,645 ÷ 2 = 250,108,322.5
If the quotient is a whole number, then 2 and 250,108,322.5 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 | 500,216,645 | |
| -1 | -500,216,645 |
Now, we try dividing 500,216,645 by 3:
500,216,645 ÷ 3 = 166,738,881.6667
If the quotient is a whole number, then 3 and 166,738,881.6667 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 | 500,216,645 | |
| -1 | -500,216,645 |
Let's try dividing by 4:
500,216,645 ÷ 4 = 125,054,161.25
If the quotient is a whole number, then 4 and 125,054,161.25 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 | 500,216,645 | |
| -1 | 500,216,645 |
If you did it right, you will end up with this table:
| 1 | 5 | 211 | 251 | 1,055 | 1,255 | 1,889 | 9,445 | 52,961 | 264,805 | 398,579 | 474,139 | 1,992,895 | 2,370,695 | 100,043,329 | 500,216,645 |
| -1 | -5 | -211 | -251 | -1,055 | -1,255 | -1,889 | -9,445 | -52,961 | -264,805 | -398,579 | -474,139 | -1,992,895 | -2,370,695 | -100,043,329 | -500,216,645 |
