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 616,164,643, 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 | 616,164,643 | |
| -1 | -616,164,643 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 616,164,643.
Example:
1 x 616,164,643 = 616,164,643
and
-1 x -616,164,643 = 616,164,643
Notice both answers equal 616,164,643
With that explanation out of the way, let's continue. Next, we take the number 616,164,643 and divide it by 2:
616,164,643 ÷ 2 = 308,082,321.5
If the quotient is a whole number, then 2 and 308,082,321.5 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 | 616,164,643 | |
| -1 | -616,164,643 |
Now, we try dividing 616,164,643 by 3:
616,164,643 ÷ 3 = 205,388,214.3333
If the quotient is a whole number, then 3 and 205,388,214.3333 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 | 616,164,643 | |
| -1 | -616,164,643 |
Let's try dividing by 4:
616,164,643 ÷ 4 = 154,041,160.75
If the quotient is a whole number, then 4 and 154,041,160.75 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 | 616,164,643 | |
| -1 | 616,164,643 |
If you did it right, you will end up with this table:
| 1 | 17 | 103 | 293 | 1,201 | 1,751 | 4,981 | 20,417 | 30,179 | 123,703 | 351,893 | 513,043 | 2,102,951 | 5,982,181 | 36,244,979 | 616,164,643 |
| -1 | -17 | -103 | -293 | -1,201 | -1,751 | -4,981 | -20,417 | -30,179 | -123,703 | -351,893 | -513,043 | -2,102,951 | -5,982,181 | -36,244,979 | -616,164,643 |
