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 275,684,695, 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 | 275,684,695 | |
| -1 | -275,684,695 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 275,684,695.
Example:
1 x 275,684,695 = 275,684,695
and
-1 x -275,684,695 = 275,684,695
Notice both answers equal 275,684,695
With that explanation out of the way, let's continue. Next, we take the number 275,684,695 and divide it by 2:
275,684,695 ÷ 2 = 137,842,347.5
If the quotient is a whole number, then 2 and 137,842,347.5 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 | 275,684,695 | |
| -1 | -275,684,695 |
Now, we try dividing 275,684,695 by 3:
275,684,695 ÷ 3 = 91,894,898.3333
If the quotient is a whole number, then 3 and 91,894,898.3333 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 | 275,684,695 | |
| -1 | -275,684,695 |
Let's try dividing by 4:
275,684,695 ÷ 4 = 68,921,173.75
If the quotient is a whole number, then 4 and 68,921,173.75 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 | 275,684,695 | |
| -1 | 275,684,695 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 13 | 55 | 65 | 143 | 715 | 385,573 | 1,927,865 | 4,241,303 | 5,012,449 | 21,206,515 | 25,062,245 | 55,136,939 | 275,684,695 |
| -1 | -5 | -11 | -13 | -55 | -65 | -143 | -715 | -385,573 | -1,927,865 | -4,241,303 | -5,012,449 | -21,206,515 | -25,062,245 | -55,136,939 | -275,684,695 |
