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 611,042,645, 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 | 611,042,645 | |
| -1 | -611,042,645 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 611,042,645.
Example:
1 x 611,042,645 = 611,042,645
and
-1 x -611,042,645 = 611,042,645
Notice both answers equal 611,042,645
With that explanation out of the way, let's continue. Next, we take the number 611,042,645 and divide it by 2:
611,042,645 ÷ 2 = 305,521,322.5
If the quotient is a whole number, then 2 and 305,521,322.5 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 | 611,042,645 | |
| -1 | -611,042,645 |
Now, we try dividing 611,042,645 by 3:
611,042,645 ÷ 3 = 203,680,881.6667
If the quotient is a whole number, then 3 and 203,680,881.6667 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 | 611,042,645 | |
| -1 | -611,042,645 |
Let's try dividing by 4:
611,042,645 ÷ 4 = 152,760,661.25
If the quotient is a whole number, then 4 and 152,760,661.25 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 | 611,042,645 | |
| -1 | 611,042,645 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 59 | 85 | 295 | 1,003 | 5,015 | 121,843 | 609,215 | 2,071,331 | 7,188,737 | 10,356,655 | 35,943,685 | 122,208,529 | 611,042,645 |
| -1 | -5 | -17 | -59 | -85 | -295 | -1,003 | -5,015 | -121,843 | -609,215 | -2,071,331 | -7,188,737 | -10,356,655 | -35,943,685 | -122,208,529 | -611,042,645 |
