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 272,616,875, 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 | 272,616,875 | |
| -1 | -272,616,875 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 272,616,875.
Example:
1 x 272,616,875 = 272,616,875
and
-1 x -272,616,875 = 272,616,875
Notice both answers equal 272,616,875
With that explanation out of the way, let's continue. Next, we take the number 272,616,875 and divide it by 2:
272,616,875 ÷ 2 = 136,308,437.5
If the quotient is a whole number, then 2 and 136,308,437.5 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 | 272,616,875 | |
| -1 | -272,616,875 |
Now, we try dividing 272,616,875 by 3:
272,616,875 ÷ 3 = 90,872,291.6667
If the quotient is a whole number, then 3 and 90,872,291.6667 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 | 272,616,875 | |
| -1 | -272,616,875 |
Let's try dividing by 4:
272,616,875 ÷ 4 = 68,154,218.75
If the quotient is a whole number, then 4 and 68,154,218.75 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 | 272,616,875 | |
| -1 | 272,616,875 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 59 | 125 | 295 | 625 | 1,475 | 7,375 | 7,393 | 36,875 | 36,965 | 184,825 | 436,187 | 924,125 | 2,180,935 | 4,620,625 | 10,904,675 | 54,523,375 | 272,616,875 |
| -1 | -5 | -25 | -59 | -125 | -295 | -625 | -1,475 | -7,375 | -7,393 | -36,875 | -36,965 | -184,825 | -436,187 | -924,125 | -2,180,935 | -4,620,625 | -10,904,675 | -54,523,375 | -272,616,875 |
