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 273,635,531, 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 | 273,635,531 | |
| -1 | -273,635,531 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 273,635,531.
Example:
1 x 273,635,531 = 273,635,531
and
-1 x -273,635,531 = 273,635,531
Notice both answers equal 273,635,531
With that explanation out of the way, let's continue. Next, we take the number 273,635,531 and divide it by 2:
273,635,531 ÷ 2 = 136,817,765.5
If the quotient is a whole number, then 2 and 136,817,765.5 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 | 273,635,531 | |
| -1 | -273,635,531 |
Now, we try dividing 273,635,531 by 3:
273,635,531 ÷ 3 = 91,211,843.6667
If the quotient is a whole number, then 3 and 91,211,843.6667 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 | 273,635,531 | |
| -1 | -273,635,531 |
Let's try dividing by 4:
273,635,531 ÷ 4 = 68,408,882.75
If the quotient is a whole number, then 4 and 68,408,882.75 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 | 273,635,531 | |
| -1 | 273,635,531 |
If you did it right, you will end up with this table:
| 1 | 13 | 23 | 43 | 299 | 559 | 989 | 12,857 | 21,283 | 276,679 | 489,509 | 915,169 | 6,363,617 | 11,897,197 | 21,048,887 | 273,635,531 |
| -1 | -13 | -23 | -43 | -299 | -559 | -989 | -12,857 | -21,283 | -276,679 | -489,509 | -915,169 | -6,363,617 | -11,897,197 | -21,048,887 | -273,635,531 |
