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 775,075, 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 | 775,075 | |
| -1 | -775,075 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 775,075.
Example:
1 x 775,075 = 775,075
and
-1 x -775,075 = 775,075
Notice both answers equal 775,075
With that explanation out of the way, let's continue. Next, we take the number 775,075 and divide it by 2:
775,075 ÷ 2 = 387,537.5
If the quotient is a whole number, then 2 and 387,537.5 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 | 775,075 | |
| -1 | -775,075 |
Now, we try dividing 775,075 by 3:
775,075 ÷ 3 = 258,358.3333
If the quotient is a whole number, then 3 and 258,358.3333 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 | 775,075 | |
| -1 | -775,075 |
Let's try dividing by 4:
775,075 ÷ 4 = 193,768.75
If the quotient is a whole number, then 4 and 193,768.75 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 | 775,075 | |
| -1 | 775,075 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 25 | 35 | 43 | 103 | 175 | 215 | 301 | 515 | 721 | 1,075 | 1,505 | 2,575 | 3,605 | 4,429 | 7,525 | 18,025 | 22,145 | 31,003 | 110,725 | 155,015 | 775,075 |
| -1 | -5 | -7 | -25 | -35 | -43 | -103 | -175 | -215 | -301 | -515 | -721 | -1,075 | -1,505 | -2,575 | -3,605 | -4,429 | -7,525 | -18,025 | -22,145 | -31,003 | -110,725 | -155,015 | -775,075 |
