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 273,571,715, 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 | 273,571,715 | |
| -1 | -273,571,715 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 273,571,715.
Example:
1 x 273,571,715 = 273,571,715
and
-1 x -273,571,715 = 273,571,715
Notice both answers equal 273,571,715
With that explanation out of the way, let's continue. Next, we take the number 273,571,715 and divide it by 2:
273,571,715 ÷ 2 = 136,785,857.5
If the quotient is a whole number, then 2 and 136,785,857.5 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 | 273,571,715 | |
| -1 | -273,571,715 |
Now, we try dividing 273,571,715 by 3:
273,571,715 ÷ 3 = 91,190,571.6667
If the quotient is a whole number, then 3 and 91,190,571.6667 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 | 273,571,715 | |
| -1 | -273,571,715 |
Let's try dividing by 4:
273,571,715 ÷ 4 = 68,392,928.75
If the quotient is a whole number, then 4 and 68,392,928.75 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 | 273,571,715 | |
| -1 | 273,571,715 |
If you did it right, you will end up with this table:
| 1 | 5 | 107 | 157 | 535 | 785 | 3,257 | 16,285 | 16,799 | 83,995 | 348,499 | 511,349 | 1,742,495 | 2,556,745 | 54,714,343 | 273,571,715 |
| -1 | -5 | -107 | -157 | -535 | -785 | -3,257 | -16,285 | -16,799 | -83,995 | -348,499 | -511,349 | -1,742,495 | -2,556,745 | -54,714,343 | -273,571,715 |
