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 271,044,851, 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 | 271,044,851 | |
| -1 | -271,044,851 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 271,044,851.
Example:
1 x 271,044,851 = 271,044,851
and
-1 x -271,044,851 = 271,044,851
Notice both answers equal 271,044,851
With that explanation out of the way, let's continue. Next, we take the number 271,044,851 and divide it by 2:
271,044,851 ÷ 2 = 135,522,425.5
If the quotient is a whole number, then 2 and 135,522,425.5 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 | 271,044,851 | |
| -1 | -271,044,851 |
Now, we try dividing 271,044,851 by 3:
271,044,851 ÷ 3 = 90,348,283.6667
If the quotient is a whole number, then 3 and 90,348,283.6667 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 | 271,044,851 | |
| -1 | -271,044,851 |
Let's try dividing by 4:
271,044,851 ÷ 4 = 67,761,212.75
If the quotient is a whole number, then 4 and 67,761,212.75 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 | 271,044,851 | |
| -1 | 271,044,851 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 77 | 113 | 791 | 1,243 | 8,701 | 31,151 | 218,057 | 342,661 | 2,398,627 | 3,520,063 | 24,640,441 | 38,720,693 | 271,044,851 |
| -1 | -7 | -11 | -77 | -113 | -791 | -1,243 | -8,701 | -31,151 | -218,057 | -342,661 | -2,398,627 | -3,520,063 | -24,640,441 | -38,720,693 | -271,044,851 |
