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 611,602,271, 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 | 611,602,271 | |
| -1 | -611,602,271 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 611,602,271.
Example:
1 x 611,602,271 = 611,602,271
and
-1 x -611,602,271 = 611,602,271
Notice both answers equal 611,602,271
With that explanation out of the way, let's continue. Next, we take the number 611,602,271 and divide it by 2:
611,602,271 ÷ 2 = 305,801,135.5
If the quotient is a whole number, then 2 and 305,801,135.5 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 | 611,602,271 | |
| -1 | -611,602,271 |
Now, we try dividing 611,602,271 by 3:
611,602,271 ÷ 3 = 203,867,423.6667
If the quotient is a whole number, then 3 and 203,867,423.6667 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 | 611,602,271 | |
| -1 | -611,602,271 |
Let's try dividing by 4:
611,602,271 ÷ 4 = 152,900,567.75
If the quotient is a whole number, then 4 and 152,900,567.75 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 | 611,602,271 | |
| -1 | 611,602,271 |
If you did it right, you will end up with this table:
| 1 | 7 | 49 | 331 | 343 | 2,317 | 5,387 | 16,219 | 37,709 | 113,533 | 263,963 | 1,783,097 | 1,847,741 | 12,481,679 | 87,371,753 | 611,602,271 |
| -1 | -7 | -49 | -331 | -343 | -2,317 | -5,387 | -16,219 | -37,709 | -113,533 | -263,963 | -1,783,097 | -1,847,741 | -12,481,679 | -87,371,753 | -611,602,271 |
