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 273,633,815, 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 | 273,633,815 | |
| -1 | -273,633,815 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 273,633,815.
Example:
1 x 273,633,815 = 273,633,815
and
-1 x -273,633,815 = 273,633,815
Notice both answers equal 273,633,815
With that explanation out of the way, let's continue. Next, we take the number 273,633,815 and divide it by 2:
273,633,815 ÷ 2 = 136,816,907.5
If the quotient is a whole number, then 2 and 136,816,907.5 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 | 273,633,815 | |
| -1 | -273,633,815 |
Now, we try dividing 273,633,815 by 3:
273,633,815 ÷ 3 = 91,211,271.6667
If the quotient is a whole number, then 3 and 91,211,271.6667 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 | 273,633,815 | |
| -1 | -273,633,815 |
Let's try dividing by 4:
273,633,815 ÷ 4 = 68,408,453.75
If the quotient is a whole number, then 4 and 68,408,453.75 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 | 273,633,815 | |
| -1 | 273,633,815 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 13 | 35 | 65 | 91 | 169 | 455 | 845 | 1,183 | 5,915 | 46,261 | 231,305 | 323,827 | 601,393 | 1,619,135 | 3,006,965 | 4,209,751 | 7,818,109 | 21,048,755 | 39,090,545 | 54,726,763 | 273,633,815 |
| -1 | -5 | -7 | -13 | -35 | -65 | -91 | -169 | -455 | -845 | -1,183 | -5,915 | -46,261 | -231,305 | -323,827 | -601,393 | -1,619,135 | -3,006,965 | -4,209,751 | -7,818,109 | -21,048,755 | -39,090,545 | -54,726,763 | -273,633,815 |
