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 276,744,083, 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 | 276,744,083 | |
| -1 | -276,744,083 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 276,744,083.
Example:
1 x 276,744,083 = 276,744,083
and
-1 x -276,744,083 = 276,744,083
Notice both answers equal 276,744,083
With that explanation out of the way, let's continue. Next, we take the number 276,744,083 and divide it by 2:
276,744,083 ÷ 2 = 138,372,041.5
If the quotient is a whole number, then 2 and 138,372,041.5 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 | 276,744,083 | |
| -1 | -276,744,083 |
Now, we try dividing 276,744,083 by 3:
276,744,083 ÷ 3 = 92,248,027.6667
If the quotient is a whole number, then 3 and 92,248,027.6667 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 | 276,744,083 | |
| -1 | -276,744,083 |
Let's try dividing by 4:
276,744,083 ÷ 4 = 69,186,020.75
If the quotient is a whole number, then 4 and 69,186,020.75 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 | 276,744,083 | |
| -1 | 276,744,083 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 77 | 1,487 | 2,417 | 10,409 | 16,357 | 16,919 | 26,587 | 114,499 | 186,109 | 3,594,079 | 25,158,553 | 39,534,869 | 276,744,083 |
| -1 | -7 | -11 | -77 | -1,487 | -2,417 | -10,409 | -16,357 | -16,919 | -26,587 | -114,499 | -186,109 | -3,594,079 | -25,158,553 | -39,534,869 | -276,744,083 |
