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 3,305,275, 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 | 3,305,275 | |
| -1 | -3,305,275 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,305,275.
Example:
1 x 3,305,275 = 3,305,275
and
-1 x -3,305,275 = 3,305,275
Notice both answers equal 3,305,275
With that explanation out of the way, let's continue. Next, we take the number 3,305,275 and divide it by 2:
3,305,275 ÷ 2 = 1,652,637.5
If the quotient is a whole number, then 2 and 1,652,637.5 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 | 3,305,275 | |
| -1 | -3,305,275 |
Now, we try dividing 3,305,275 by 3:
3,305,275 ÷ 3 = 1,101,758.3333
If the quotient is a whole number, then 3 and 1,101,758.3333 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 | 3,305,275 | |
| -1 | -3,305,275 |
Let's try dividing by 4:
3,305,275 ÷ 4 = 826,318.75
If the quotient is a whole number, then 4 and 826,318.75 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 | 3,305,275 | |
| -1 | 3,305,275 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 29 | 47 | 97 | 145 | 235 | 485 | 725 | 1,175 | 1,363 | 2,425 | 2,813 | 4,559 | 6,815 | 14,065 | 22,795 | 34,075 | 70,325 | 113,975 | 132,211 | 661,055 | 3,305,275 |
| -1 | -5 | -25 | -29 | -47 | -97 | -145 | -235 | -485 | -725 | -1,175 | -1,363 | -2,425 | -2,813 | -4,559 | -6,815 | -14,065 | -22,795 | -34,075 | -70,325 | -113,975 | -132,211 | -661,055 | -3,305,275 |
