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 754,775, 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 | 754,775 | |
| -1 | -754,775 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 754,775.
Example:
1 x 754,775 = 754,775
and
-1 x -754,775 = 754,775
Notice both answers equal 754,775
With that explanation out of the way, let's continue. Next, we take the number 754,775 and divide it by 2:
754,775 ÷ 2 = 377,387.5
If the quotient is a whole number, then 2 and 377,387.5 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 | 754,775 | |
| -1 | -754,775 |
Now, we try dividing 754,775 by 3:
754,775 ÷ 3 = 251,591.6667
If the quotient is a whole number, then 3 and 251,591.6667 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 | 754,775 | |
| -1 | -754,775 |
Let's try dividing by 4:
754,775 ÷ 4 = 188,693.75
If the quotient is a whole number, then 4 and 188,693.75 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 | 754,775 | |
| -1 | 754,775 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 19 | 25 | 35 | 95 | 133 | 175 | 227 | 475 | 665 | 1,135 | 1,589 | 3,325 | 4,313 | 5,675 | 7,945 | 21,565 | 30,191 | 39,725 | 107,825 | 150,955 | 754,775 |
| -1 | -5 | -7 | -19 | -25 | -35 | -95 | -133 | -175 | -227 | -475 | -665 | -1,135 | -1,589 | -3,325 | -4,313 | -5,675 | -7,945 | -21,565 | -30,191 | -39,725 | -107,825 | -150,955 | -754,775 |
