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 616,014,301, 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 | 616,014,301 | |
| -1 | -616,014,301 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 616,014,301.
Example:
1 x 616,014,301 = 616,014,301
and
-1 x -616,014,301 = 616,014,301
Notice both answers equal 616,014,301
With that explanation out of the way, let's continue. Next, we take the number 616,014,301 and divide it by 2:
616,014,301 ÷ 2 = 308,007,150.5
If the quotient is a whole number, then 2 and 308,007,150.5 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 | 616,014,301 | |
| -1 | -616,014,301 |
Now, we try dividing 616,014,301 by 3:
616,014,301 ÷ 3 = 205,338,100.3333
If the quotient is a whole number, then 3 and 205,338,100.3333 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 | 616,014,301 | |
| -1 | -616,014,301 |
Let's try dividing by 4:
616,014,301 ÷ 4 = 154,003,575.25
If the quotient is a whole number, then 4 and 154,003,575.25 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 | 616,014,301 | |
| -1 | 616,014,301 |
If you did it right, you will end up with this table:
| 1 | 7 | 89 | 107 | 623 | 749 | 9,241 | 9,523 | 64,687 | 66,661 | 822,449 | 988,787 | 5,757,143 | 6,921,509 | 88,002,043 | 616,014,301 |
| -1 | -7 | -89 | -107 | -623 | -749 | -9,241 | -9,523 | -64,687 | -66,661 | -822,449 | -988,787 | -5,757,143 | -6,921,509 | -88,002,043 | -616,014,301 |
