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 273,562,655, 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 | 273,562,655 | |
| -1 | -273,562,655 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 273,562,655.
Example:
1 x 273,562,655 = 273,562,655
and
-1 x -273,562,655 = 273,562,655
Notice both answers equal 273,562,655
With that explanation out of the way, let's continue. Next, we take the number 273,562,655 and divide it by 2:
273,562,655 ÷ 2 = 136,781,327.5
If the quotient is a whole number, then 2 and 136,781,327.5 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 | 273,562,655 | |
| -1 | -273,562,655 |
Now, we try dividing 273,562,655 by 3:
273,562,655 ÷ 3 = 91,187,551.6667
If the quotient is a whole number, then 3 and 91,187,551.6667 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 | 273,562,655 | |
| -1 | -273,562,655 |
Let's try dividing by 4:
273,562,655 ÷ 4 = 68,390,663.75
If the quotient is a whole number, then 4 and 68,390,663.75 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 | 273,562,655 | |
| -1 | 273,562,655 |
If you did it right, you will end up with this table:
| 1 | 5 | 29 | 145 | 347 | 1,735 | 5,437 | 10,063 | 27,185 | 50,315 | 157,673 | 788,365 | 1,886,639 | 9,433,195 | 54,712,531 | 273,562,655 |
| -1 | -5 | -29 | -145 | -347 | -1,735 | -5,437 | -10,063 | -27,185 | -50,315 | -157,673 | -788,365 | -1,886,639 | -9,433,195 | -54,712,531 | -273,562,655 |
