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 612,052,555, 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 | 612,052,555 | |
| -1 | -612,052,555 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 612,052,555.
Example:
1 x 612,052,555 = 612,052,555
and
-1 x -612,052,555 = 612,052,555
Notice both answers equal 612,052,555
With that explanation out of the way, let's continue. Next, we take the number 612,052,555 and divide it by 2:
612,052,555 ÷ 2 = 306,026,277.5
If the quotient is a whole number, then 2 and 306,026,277.5 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 | 612,052,555 | |
| -1 | -612,052,555 |
Now, we try dividing 612,052,555 by 3:
612,052,555 ÷ 3 = 204,017,518.3333
If the quotient is a whole number, then 3 and 204,017,518.3333 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 | 612,052,555 | |
| -1 | -612,052,555 |
Let's try dividing by 4:
612,052,555 ÷ 4 = 153,013,138.75
If the quotient is a whole number, then 4 and 153,013,138.75 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 | 612,052,555 | |
| -1 | 612,052,555 |
If you did it right, you will end up with this table:
| 1 | 5 | 89 | 233 | 445 | 1,165 | 5,903 | 20,737 | 29,515 | 103,685 | 525,367 | 1,375,399 | 2,626,835 | 6,876,995 | 122,410,511 | 612,052,555 |
| -1 | -5 | -89 | -233 | -445 | -1,165 | -5,903 | -20,737 | -29,515 | -103,685 | -525,367 | -1,375,399 | -2,626,835 | -6,876,995 | -122,410,511 | -612,052,555 |
