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 612,131,609, 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 | 612,131,609 | |
| -1 | -612,131,609 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 612,131,609.
Example:
1 x 612,131,609 = 612,131,609
and
-1 x -612,131,609 = 612,131,609
Notice both answers equal 612,131,609
With that explanation out of the way, let's continue. Next, we take the number 612,131,609 and divide it by 2:
612,131,609 ÷ 2 = 306,065,804.5
If the quotient is a whole number, then 2 and 306,065,804.5 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 | 612,131,609 | |
| -1 | -612,131,609 |
Now, we try dividing 612,131,609 by 3:
612,131,609 ÷ 3 = 204,043,869.6667
If the quotient is a whole number, then 3 and 204,043,869.6667 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 | 612,131,609 | |
| -1 | -612,131,609 |
Let's try dividing by 4:
612,131,609 ÷ 4 = 153,032,902.25
If the quotient is a whole number, then 4 and 153,032,902.25 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 | 612,131,609 | |
| -1 | 612,131,609 |
If you did it right, you will end up with this table:
| 1 | 53 | 101 | 173 | 661 | 5,353 | 9,169 | 17,473 | 35,033 | 66,761 | 114,353 | 926,069 | 3,538,333 | 6,060,709 | 11,549,653 | 612,131,609 |
| -1 | -53 | -101 | -173 | -661 | -5,353 | -9,169 | -17,473 | -35,033 | -66,761 | -114,353 | -926,069 | -3,538,333 | -6,060,709 | -11,549,653 | -612,131,609 |
