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 273,077,651, 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 | 273,077,651 | |
| -1 | -273,077,651 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 273,077,651.
Example:
1 x 273,077,651 = 273,077,651
and
-1 x -273,077,651 = 273,077,651
Notice both answers equal 273,077,651
With that explanation out of the way, let's continue. Next, we take the number 273,077,651 and divide it by 2:
273,077,651 ÷ 2 = 136,538,825.5
If the quotient is a whole number, then 2 and 136,538,825.5 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 | 273,077,651 | |
| -1 | -273,077,651 |
Now, we try dividing 273,077,651 by 3:
273,077,651 ÷ 3 = 91,025,883.6667
If the quotient is a whole number, then 3 and 91,025,883.6667 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 | 273,077,651 | |
| -1 | -273,077,651 |
Let's try dividing by 4:
273,077,651 ÷ 4 = 68,269,412.75
If the quotient is a whole number, then 4 and 68,269,412.75 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 | 273,077,651 | |
| -1 | 273,077,651 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 77 | 523 | 3,661 | 5,753 | 6,781 | 40,271 | 47,467 | 74,591 | 522,137 | 3,546,463 | 24,825,241 | 39,011,093 | 273,077,651 |
| -1 | -7 | -11 | -77 | -523 | -3,661 | -5,753 | -6,781 | -40,271 | -47,467 | -74,591 | -522,137 | -3,546,463 | -24,825,241 | -39,011,093 | -273,077,651 |
