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 2,300,305, 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 | 2,300,305 | |
| -1 | -2,300,305 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 2,300,305.
Example:
1 x 2,300,305 = 2,300,305
and
-1 x -2,300,305 = 2,300,305
Notice both answers equal 2,300,305
With that explanation out of the way, let's continue. Next, we take the number 2,300,305 and divide it by 2:
2,300,305 ÷ 2 = 1,150,152.5
If the quotient is a whole number, then 2 and 1,150,152.5 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 | 2,300,305 | |
| -1 | -2,300,305 |
Now, we try dividing 2,300,305 by 3:
2,300,305 ÷ 3 = 766,768.3333
If the quotient is a whole number, then 3 and 766,768.3333 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 | 2,300,305 | |
| -1 | -2,300,305 |
Let's try dividing by 4:
2,300,305 ÷ 4 = 575,076.25
If the quotient is a whole number, then 4 and 575,076.25 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 | 2,300,305 | |
| -1 | 2,300,305 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 41 | 49 | 205 | 229 | 245 | 287 | 1,145 | 1,435 | 1,603 | 2,009 | 8,015 | 9,389 | 10,045 | 11,221 | 46,945 | 56,105 | 65,723 | 328,615 | 460,061 | 2,300,305 |
| -1 | -5 | -7 | -35 | -41 | -49 | -205 | -229 | -245 | -287 | -1,145 | -1,435 | -1,603 | -2,009 | -8,015 | -9,389 | -10,045 | -11,221 | -46,945 | -56,105 | -65,723 | -328,615 | -460,061 | -2,300,305 |
