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 611,602,277, 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 | 611,602,277 | |
| -1 | -611,602,277 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 611,602,277.
Example:
1 x 611,602,277 = 611,602,277
and
-1 x -611,602,277 = 611,602,277
Notice both answers equal 611,602,277
With that explanation out of the way, let's continue. Next, we take the number 611,602,277 and divide it by 2:
611,602,277 ÷ 2 = 305,801,138.5
If the quotient is a whole number, then 2 and 305,801,138.5 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 | 611,602,277 | |
| -1 | -611,602,277 |
Now, we try dividing 611,602,277 by 3:
611,602,277 ÷ 3 = 203,867,425.6667
If the quotient is a whole number, then 3 and 203,867,425.6667 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 | 611,602,277 | |
| -1 | -611,602,277 |
Let's try dividing by 4:
611,602,277 ÷ 4 = 152,900,569.25
If the quotient is a whole number, then 4 and 152,900,569.25 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 | 611,602,277 | |
| -1 | 611,602,277 |
If you did it right, you will end up with this table:
| 1 | 11 | 13 | 143 | 421 | 4,631 | 5,473 | 10,159 | 60,203 | 111,749 | 132,067 | 1,452,737 | 4,276,939 | 47,046,329 | 55,600,207 | 611,602,277 |
| -1 | -11 | -13 | -143 | -421 | -4,631 | -5,473 | -10,159 | -60,203 | -111,749 | -132,067 | -1,452,737 | -4,276,939 | -47,046,329 | -55,600,207 | -611,602,277 |
