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 276,007,927, 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 | 276,007,927 | |
| -1 | -276,007,927 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 276,007,927.
Example:
1 x 276,007,927 = 276,007,927
and
-1 x -276,007,927 = 276,007,927
Notice both answers equal 276,007,927
With that explanation out of the way, let's continue. Next, we take the number 276,007,927 and divide it by 2:
276,007,927 ÷ 2 = 138,003,963.5
If the quotient is a whole number, then 2 and 138,003,963.5 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 | 276,007,927 | |
| -1 | -276,007,927 |
Now, we try dividing 276,007,927 by 3:
276,007,927 ÷ 3 = 92,002,642.3333
If the quotient is a whole number, then 3 and 92,002,642.3333 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 | 276,007,927 | |
| -1 | -276,007,927 |
Let's try dividing by 4:
276,007,927 ÷ 4 = 69,001,981.75
If the quotient is a whole number, then 4 and 69,001,981.75 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 | 276,007,927 | |
| -1 | 276,007,927 |
If you did it right, you will end up with this table:
| 1 | 13 | 19 | 43 | 169 | 247 | 559 | 817 | 1,999 | 3,211 | 7,267 | 10,621 | 25,987 | 37,981 | 85,957 | 138,073 | 337,831 | 493,753 | 1,117,441 | 1,633,183 | 6,418,789 | 14,526,733 | 21,231,379 | 276,007,927 |
| -1 | -13 | -19 | -43 | -169 | -247 | -559 | -817 | -1,999 | -3,211 | -7,267 | -10,621 | -25,987 | -37,981 | -85,957 | -138,073 | -337,831 | -493,753 | -1,117,441 | -1,633,183 | -6,418,789 | -14,526,733 | -21,231,379 | -276,007,927 |
