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 273,122,045, 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 | 273,122,045 | |
| -1 | -273,122,045 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 273,122,045.
Example:
1 x 273,122,045 = 273,122,045
and
-1 x -273,122,045 = 273,122,045
Notice both answers equal 273,122,045
With that explanation out of the way, let's continue. Next, we take the number 273,122,045 and divide it by 2:
273,122,045 ÷ 2 = 136,561,022.5
If the quotient is a whole number, then 2 and 136,561,022.5 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 | 273,122,045 | |
| -1 | -273,122,045 |
Now, we try dividing 273,122,045 by 3:
273,122,045 ÷ 3 = 91,040,681.6667
If the quotient is a whole number, then 3 and 91,040,681.6667 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 | 273,122,045 | |
| -1 | -273,122,045 |
Let's try dividing by 4:
273,122,045 ÷ 4 = 68,280,511.25
If the quotient is a whole number, then 4 and 68,280,511.25 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 | 273,122,045 | |
| -1 | 273,122,045 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 1,879 | 4,153 | 9,395 | 13,153 | 20,765 | 29,071 | 65,765 | 145,355 | 7,803,487 | 39,017,435 | 54,624,409 | 273,122,045 |
| -1 | -5 | -7 | -35 | -1,879 | -4,153 | -9,395 | -13,153 | -20,765 | -29,071 | -65,765 | -145,355 | -7,803,487 | -39,017,435 | -54,624,409 | -273,122,045 |
