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 612,041,735, 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 | 612,041,735 | |
| -1 | -612,041,735 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 612,041,735.
Example:
1 x 612,041,735 = 612,041,735
and
-1 x -612,041,735 = 612,041,735
Notice both answers equal 612,041,735
With that explanation out of the way, let's continue. Next, we take the number 612,041,735 and divide it by 2:
612,041,735 ÷ 2 = 306,020,867.5
If the quotient is a whole number, then 2 and 306,020,867.5 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 | 612,041,735 | |
| -1 | -612,041,735 |
Now, we try dividing 612,041,735 by 3:
612,041,735 ÷ 3 = 204,013,911.6667
If the quotient is a whole number, then 3 and 204,013,911.6667 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 | 612,041,735 | |
| -1 | -612,041,735 |
Let's try dividing by 4:
612,041,735 ÷ 4 = 153,010,433.75
If the quotient is a whole number, then 4 and 153,010,433.75 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 | 612,041,735 | |
| -1 | 612,041,735 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 85 | 157 | 785 | 2,669 | 13,345 | 45,863 | 229,315 | 779,671 | 3,898,355 | 7,200,491 | 36,002,455 | 122,408,347 | 612,041,735 |
| -1 | -5 | -17 | -85 | -157 | -785 | -2,669 | -13,345 | -45,863 | -229,315 | -779,671 | -3,898,355 | -7,200,491 | -36,002,455 | -122,408,347 | -612,041,735 |
