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 276,751,565, 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 | 276,751,565 | |
| -1 | -276,751,565 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 276,751,565.
Example:
1 x 276,751,565 = 276,751,565
and
-1 x -276,751,565 = 276,751,565
Notice both answers equal 276,751,565
With that explanation out of the way, let's continue. Next, we take the number 276,751,565 and divide it by 2:
276,751,565 ÷ 2 = 138,375,782.5
If the quotient is a whole number, then 2 and 138,375,782.5 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 | 276,751,565 | |
| -1 | -276,751,565 |
Now, we try dividing 276,751,565 by 3:
276,751,565 ÷ 3 = 92,250,521.6667
If the quotient is a whole number, then 3 and 92,250,521.6667 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 | 276,751,565 | |
| -1 | -276,751,565 |
Let's try dividing by 4:
276,751,565 ÷ 4 = 69,187,891.25
If the quotient is a whole number, then 4 and 69,187,891.25 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 | 276,751,565 | |
| -1 | 276,751,565 |
If you did it right, you will end up with this table:
| 1 | 5 | 167 | 431 | 769 | 835 | 2,155 | 3,845 | 71,977 | 128,423 | 331,439 | 359,885 | 642,115 | 1,657,195 | 55,350,313 | 276,751,565 |
| -1 | -5 | -167 | -431 | -769 | -835 | -2,155 | -3,845 | -71,977 | -128,423 | -331,439 | -359,885 | -642,115 | -1,657,195 | -55,350,313 | -276,751,565 |
