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 616,514,503, 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 | 616,514,503 | |
| -1 | -616,514,503 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 616,514,503.
Example:
1 x 616,514,503 = 616,514,503
and
-1 x -616,514,503 = 616,514,503
Notice both answers equal 616,514,503
With that explanation out of the way, let's continue. Next, we take the number 616,514,503 and divide it by 2:
616,514,503 ÷ 2 = 308,257,251.5
If the quotient is a whole number, then 2 and 308,257,251.5 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 | 616,514,503 | |
| -1 | -616,514,503 |
Now, we try dividing 616,514,503 by 3:
616,514,503 ÷ 3 = 205,504,834.3333
If the quotient is a whole number, then 3 and 205,504,834.3333 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 | 616,514,503 | |
| -1 | -616,514,503 |
Let's try dividing by 4:
616,514,503 ÷ 4 = 154,128,625.75
If the quotient is a whole number, then 4 and 154,128,625.75 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 | 616,514,503 | |
| -1 | 616,514,503 |
If you did it right, you will end up with this table:
| 1 | 11 | 17 | 67 | 187 | 737 | 1,139 | 12,529 | 49,207 | 541,277 | 836,519 | 3,296,869 | 9,201,709 | 36,265,559 | 56,046,773 | 616,514,503 |
| -1 | -11 | -17 | -67 | -187 | -737 | -1,139 | -12,529 | -49,207 | -541,277 | -836,519 | -3,296,869 | -9,201,709 | -36,265,559 | -56,046,773 | -616,514,503 |
