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 272,068,115, 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 | 272,068,115 | |
| -1 | -272,068,115 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 272,068,115.
Example:
1 x 272,068,115 = 272,068,115
and
-1 x -272,068,115 = 272,068,115
Notice both answers equal 272,068,115
With that explanation out of the way, let's continue. Next, we take the number 272,068,115 and divide it by 2:
272,068,115 ÷ 2 = 136,034,057.5
If the quotient is a whole number, then 2 and 136,034,057.5 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 | 272,068,115 | |
| -1 | -272,068,115 |
Now, we try dividing 272,068,115 by 3:
272,068,115 ÷ 3 = 90,689,371.6667
If the quotient is a whole number, then 3 and 90,689,371.6667 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 | 272,068,115 | |
| -1 | -272,068,115 |
Let's try dividing by 4:
272,068,115 ÷ 4 = 68,017,028.75
If the quotient is a whole number, then 4 and 68,017,028.75 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 | 272,068,115 | |
| -1 | 272,068,115 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 709 | 3,545 | 6,977 | 7,799 | 34,885 | 38,995 | 76,747 | 383,735 | 4,946,693 | 24,733,465 | 54,413,623 | 272,068,115 |
| -1 | -5 | -11 | -55 | -709 | -3,545 | -6,977 | -7,799 | -34,885 | -38,995 | -76,747 | -383,735 | -4,946,693 | -24,733,465 | -54,413,623 | -272,068,115 |
