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 616,103,243, 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 | 616,103,243 | |
| -1 | -616,103,243 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 616,103,243.
Example:
1 x 616,103,243 = 616,103,243
and
-1 x -616,103,243 = 616,103,243
Notice both answers equal 616,103,243
With that explanation out of the way, let's continue. Next, we take the number 616,103,243 and divide it by 2:
616,103,243 ÷ 2 = 308,051,621.5
If the quotient is a whole number, then 2 and 308,051,621.5 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 | 616,103,243 | |
| -1 | -616,103,243 |
Now, we try dividing 616,103,243 by 3:
616,103,243 ÷ 3 = 205,367,747.6667
If the quotient is a whole number, then 3 and 205,367,747.6667 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 | 616,103,243 | |
| -1 | -616,103,243 |
Let's try dividing by 4:
616,103,243 ÷ 4 = 154,025,810.75
If the quotient is a whole number, then 4 and 154,025,810.75 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 | 616,103,243 | |
| -1 | 616,103,243 |
If you did it right, you will end up with this table:
| 1 | 7 | 37 | 259 | 541 | 3,787 | 4,397 | 20,017 | 30,779 | 140,119 | 162,689 | 1,138,823 | 2,378,777 | 16,651,439 | 88,014,749 | 616,103,243 |
| -1 | -7 | -37 | -259 | -541 | -3,787 | -4,397 | -20,017 | -30,779 | -140,119 | -162,689 | -1,138,823 | -2,378,777 | -16,651,439 | -88,014,749 | -616,103,243 |
