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 276,114,787, 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 | 276,114,787 | |
| -1 | -276,114,787 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 276,114,787.
Example:
1 x 276,114,787 = 276,114,787
and
-1 x -276,114,787 = 276,114,787
Notice both answers equal 276,114,787
With that explanation out of the way, let's continue. Next, we take the number 276,114,787 and divide it by 2:
276,114,787 ÷ 2 = 138,057,393.5
If the quotient is a whole number, then 2 and 138,057,393.5 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 | 276,114,787 | |
| -1 | -276,114,787 |
Now, we try dividing 276,114,787 by 3:
276,114,787 ÷ 3 = 92,038,262.3333
If the quotient is a whole number, then 3 and 92,038,262.3333 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 | 276,114,787 | |
| -1 | -276,114,787 |
Let's try dividing by 4:
276,114,787 ÷ 4 = 69,028,696.75
If the quotient is a whole number, then 4 and 69,028,696.75 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 | 276,114,787 | |
| -1 | 276,114,787 |
If you did it right, you will end up with this table:
| 1 | 13 | 41 | 533 | 701 | 739 | 9,113 | 9,607 | 28,741 | 30,299 | 373,633 | 393,887 | 518,039 | 6,734,507 | 21,239,599 | 276,114,787 |
| -1 | -13 | -41 | -533 | -701 | -739 | -9,113 | -9,607 | -28,741 | -30,299 | -373,633 | -393,887 | -518,039 | -6,734,507 | -21,239,599 | -276,114,787 |
