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 612,560,123, 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 | 612,560,123 | |
| -1 | -612,560,123 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 612,560,123.
Example:
1 x 612,560,123 = 612,560,123
and
-1 x -612,560,123 = 612,560,123
Notice both answers equal 612,560,123
With that explanation out of the way, let's continue. Next, we take the number 612,560,123 and divide it by 2:
612,560,123 ÷ 2 = 306,280,061.5
If the quotient is a whole number, then 2 and 306,280,061.5 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 | 612,560,123 | |
| -1 | -612,560,123 |
Now, we try dividing 612,560,123 by 3:
612,560,123 ÷ 3 = 204,186,707.6667
If the quotient is a whole number, then 3 and 204,186,707.6667 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 | 612,560,123 | |
| -1 | -612,560,123 |
Let's try dividing by 4:
612,560,123 ÷ 4 = 153,140,030.75
If the quotient is a whole number, then 4 and 153,140,030.75 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 | 612,560,123 | |
| -1 | 612,560,123 |
If you did it right, you will end up with this table:
| 1 | 7 | 37 | 49 | 259 | 1,813 | 337,871 | 2,365,097 | 12,501,227 | 16,555,679 | 87,508,589 | 612,560,123 |
| -1 | -7 | -37 | -49 | -259 | -1,813 | -337,871 | -2,365,097 | -12,501,227 | -16,555,679 | -87,508,589 | -612,560,123 |
