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 273,125,047, 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 | 273,125,047 | |
| -1 | -273,125,047 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 273,125,047.
Example:
1 x 273,125,047 = 273,125,047
and
-1 x -273,125,047 = 273,125,047
Notice both answers equal 273,125,047
With that explanation out of the way, let's continue. Next, we take the number 273,125,047 and divide it by 2:
273,125,047 ÷ 2 = 136,562,523.5
If the quotient is a whole number, then 2 and 136,562,523.5 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 | 273,125,047 | |
| -1 | -273,125,047 |
Now, we try dividing 273,125,047 by 3:
273,125,047 ÷ 3 = 91,041,682.3333
If the quotient is a whole number, then 3 and 91,041,682.3333 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 | 273,125,047 | |
| -1 | -273,125,047 |
Let's try dividing by 4:
273,125,047 ÷ 4 = 68,281,261.75
If the quotient is a whole number, then 4 and 68,281,261.75 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 | 273,125,047 | |
| -1 | 273,125,047 |
If you did it right, you will end up with this table:
| 1 | 13 | 73 | 277 | 949 | 1,039 | 3,601 | 13,507 | 20,221 | 75,847 | 262,873 | 287,803 | 986,011 | 3,741,439 | 21,009,619 | 273,125,047 |
| -1 | -13 | -73 | -277 | -949 | -1,039 | -3,601 | -13,507 | -20,221 | -75,847 | -262,873 | -287,803 | -986,011 | -3,741,439 | -21,009,619 | -273,125,047 |
