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 276,622,463, 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 | 276,622,463 | |
| -1 | -276,622,463 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 276,622,463.
Example:
1 x 276,622,463 = 276,622,463
and
-1 x -276,622,463 = 276,622,463
Notice both answers equal 276,622,463
With that explanation out of the way, let's continue. Next, we take the number 276,622,463 and divide it by 2:
276,622,463 ÷ 2 = 138,311,231.5
If the quotient is a whole number, then 2 and 138,311,231.5 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 | 276,622,463 | |
| -1 | -276,622,463 |
Now, we try dividing 276,622,463 by 3:
276,622,463 ÷ 3 = 92,207,487.6667
If the quotient is a whole number, then 3 and 92,207,487.6667 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 | 276,622,463 | |
| -1 | -276,622,463 |
Let's try dividing by 4:
276,622,463 ÷ 4 = 69,155,615.75
If the quotient is a whole number, then 4 and 69,155,615.75 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 | 276,622,463 | |
| -1 | 276,622,463 |
If you did it right, you will end up with this table:
| 1 | 13 | 19 | 247 | 877 | 1,277 | 11,401 | 16,601 | 16,663 | 24,263 | 216,619 | 315,419 | 1,119,929 | 14,559,077 | 21,278,651 | 276,622,463 |
| -1 | -13 | -19 | -247 | -877 | -1,277 | -11,401 | -16,601 | -16,663 | -24,263 | -216,619 | -315,419 | -1,119,929 | -14,559,077 | -21,278,651 | -276,622,463 |
