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 612,070,055, 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 | 612,070,055 | |
| -1 | -612,070,055 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 612,070,055.
Example:
1 x 612,070,055 = 612,070,055
and
-1 x -612,070,055 = 612,070,055
Notice both answers equal 612,070,055
With that explanation out of the way, let's continue. Next, we take the number 612,070,055 and divide it by 2:
612,070,055 ÷ 2 = 306,035,027.5
If the quotient is a whole number, then 2 and 306,035,027.5 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 | 612,070,055 | |
| -1 | -612,070,055 |
Now, we try dividing 612,070,055 by 3:
612,070,055 ÷ 3 = 204,023,351.6667
If the quotient is a whole number, then 3 and 204,023,351.6667 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 | 612,070,055 | |
| -1 | -612,070,055 |
Let's try dividing by 4:
612,070,055 ÷ 4 = 153,017,513.75
If the quotient is a whole number, then 4 and 153,017,513.75 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 | 612,070,055 | |
| -1 | 612,070,055 |
If you did it right, you will end up with this table:
| 1 | 5 | 71 | 229 | 355 | 1,145 | 7,529 | 16,259 | 37,645 | 81,295 | 534,559 | 1,724,141 | 2,672,795 | 8,620,705 | 122,414,011 | 612,070,055 |
| -1 | -5 | -71 | -229 | -355 | -1,145 | -7,529 | -16,259 | -37,645 | -81,295 | -534,559 | -1,724,141 | -2,672,795 | -8,620,705 | -122,414,011 | -612,070,055 |
