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 612,704,077, 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 | 612,704,077 | |
| -1 | -612,704,077 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 612,704,077.
Example:
1 x 612,704,077 = 612,704,077
and
-1 x -612,704,077 = 612,704,077
Notice both answers equal 612,704,077
With that explanation out of the way, let's continue. Next, we take the number 612,704,077 and divide it by 2:
612,704,077 ÷ 2 = 306,352,038.5
If the quotient is a whole number, then 2 and 306,352,038.5 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 | 612,704,077 | |
| -1 | -612,704,077 |
Now, we try dividing 612,704,077 by 3:
612,704,077 ÷ 3 = 204,234,692.3333
If the quotient is a whole number, then 3 and 204,234,692.3333 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 | 612,704,077 | |
| -1 | -612,704,077 |
Let's try dividing by 4:
612,704,077 ÷ 4 = 153,176,019.25
If the quotient is a whole number, then 4 and 153,176,019.25 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 | 612,704,077 | |
| -1 | 612,704,077 |
If you did it right, you will end up with this table:
| 1 | 19 | 101 | 139 | 1,919 | 2,297 | 2,641 | 14,039 | 43,643 | 231,997 | 266,741 | 319,283 | 4,407,943 | 6,066,377 | 32,247,583 | 612,704,077 |
| -1 | -19 | -101 | -139 | -1,919 | -2,297 | -2,641 | -14,039 | -43,643 | -231,997 | -266,741 | -319,283 | -4,407,943 | -6,066,377 | -32,247,583 | -612,704,077 |
