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 273,765,271, 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 | 273,765,271 | |
| -1 | -273,765,271 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 273,765,271.
Example:
1 x 273,765,271 = 273,765,271
and
-1 x -273,765,271 = 273,765,271
Notice both answers equal 273,765,271
With that explanation out of the way, let's continue. Next, we take the number 273,765,271 and divide it by 2:
273,765,271 ÷ 2 = 136,882,635.5
If the quotient is a whole number, then 2 and 136,882,635.5 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 | 273,765,271 | |
| -1 | -273,765,271 |
Now, we try dividing 273,765,271 by 3:
273,765,271 ÷ 3 = 91,255,090.3333
If the quotient is a whole number, then 3 and 91,255,090.3333 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 | 273,765,271 | |
| -1 | -273,765,271 |
Let's try dividing by 4:
273,765,271 ÷ 4 = 68,441,317.75
If the quotient is a whole number, then 4 and 68,441,317.75 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 | 273,765,271 | |
| -1 | 273,765,271 |
If you did it right, you will end up with this table:
| 1 | 13 | 47 | 167 | 611 | 2,171 | 2,683 | 7,849 | 34,879 | 102,037 | 126,101 | 448,061 | 1,639,313 | 5,824,793 | 21,058,867 | 273,765,271 |
| -1 | -13 | -47 | -167 | -611 | -2,171 | -2,683 | -7,849 | -34,879 | -102,037 | -126,101 | -448,061 | -1,639,313 | -5,824,793 | -21,058,867 | -273,765,271 |
