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 277,516,823, 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 | 277,516,823 | |
| -1 | -277,516,823 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 277,516,823.
Example:
1 x 277,516,823 = 277,516,823
and
-1 x -277,516,823 = 277,516,823
Notice both answers equal 277,516,823
With that explanation out of the way, let's continue. Next, we take the number 277,516,823 and divide it by 2:
277,516,823 ÷ 2 = 138,758,411.5
If the quotient is a whole number, then 2 and 138,758,411.5 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 | 277,516,823 | |
| -1 | -277,516,823 |
Now, we try dividing 277,516,823 by 3:
277,516,823 ÷ 3 = 92,505,607.6667
If the quotient is a whole number, then 3 and 92,505,607.6667 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 | 277,516,823 | |
| -1 | -277,516,823 |
Let's try dividing by 4:
277,516,823 ÷ 4 = 69,379,205.75
If the quotient is a whole number, then 4 and 69,379,205.75 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 | 277,516,823 | |
| -1 | 277,516,823 |
If you did it right, you will end up with this table:
| 1 | 17 | 41 | 193 | 697 | 2,063 | 3,281 | 7,913 | 35,071 | 84,583 | 134,521 | 398,159 | 1,437,911 | 6,768,703 | 16,324,519 | 277,516,823 |
| -1 | -17 | -41 | -193 | -697 | -2,063 | -3,281 | -7,913 | -35,071 | -84,583 | -134,521 | -398,159 | -1,437,911 | -6,768,703 | -16,324,519 | -277,516,823 |
