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 719,075, 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 | 719,075 | |
| -1 | -719,075 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 719,075.
Example:
1 x 719,075 = 719,075
and
-1 x -719,075 = 719,075
Notice both answers equal 719,075
With that explanation out of the way, let's continue. Next, we take the number 719,075 and divide it by 2:
719,075 ÷ 2 = 359,537.5
If the quotient is a whole number, then 2 and 359,537.5 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 | 719,075 | |
| -1 | -719,075 |
Now, we try dividing 719,075 by 3:
719,075 ÷ 3 = 239,691.6667
If the quotient is a whole number, then 3 and 239,691.6667 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 | 719,075 | |
| -1 | -719,075 |
Let's try dividing by 4:
719,075 ÷ 4 = 179,768.75
If the quotient is a whole number, then 4 and 179,768.75 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 | 719,075 | |
| -1 | 719,075 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 25 | 35 | 49 | 175 | 245 | 587 | 1,225 | 2,935 | 4,109 | 14,675 | 20,545 | 28,763 | 102,725 | 143,815 | 719,075 |
| -1 | -5 | -7 | -25 | -35 | -49 | -175 | -245 | -587 | -1,225 | -2,935 | -4,109 | -14,675 | -20,545 | -28,763 | -102,725 | -143,815 | -719,075 |
