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 277,714,115, 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 | 277,714,115 | |
| -1 | -277,714,115 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 277,714,115.
Example:
1 x 277,714,115 = 277,714,115
and
-1 x -277,714,115 = 277,714,115
Notice both answers equal 277,714,115
With that explanation out of the way, let's continue. Next, we take the number 277,714,115 and divide it by 2:
277,714,115 ÷ 2 = 138,857,057.5
If the quotient is a whole number, then 2 and 138,857,057.5 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 | 277,714,115 | |
| -1 | -277,714,115 |
Now, we try dividing 277,714,115 by 3:
277,714,115 ÷ 3 = 92,571,371.6667
If the quotient is a whole number, then 3 and 92,571,371.6667 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 | 277,714,115 | |
| -1 | -277,714,115 |
Let's try dividing by 4:
277,714,115 ÷ 4 = 69,428,528.75
If the quotient is a whole number, then 4 and 69,428,528.75 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 | 277,714,115 | |
| -1 | 277,714,115 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 41 | 49 | 205 | 245 | 287 | 1,435 | 2,009 | 10,045 | 27,647 | 138,235 | 193,529 | 967,645 | 1,133,527 | 1,354,703 | 5,667,635 | 6,773,515 | 7,934,689 | 39,673,445 | 55,542,823 | 277,714,115 |
| -1 | -5 | -7 | -35 | -41 | -49 | -205 | -245 | -287 | -1,435 | -2,009 | -10,045 | -27,647 | -138,235 | -193,529 | -967,645 | -1,133,527 | -1,354,703 | -5,667,635 | -6,773,515 | -7,934,689 | -39,673,445 | -55,542,823 | -277,714,115 |
