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 12,422,305, 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 | 12,422,305 | |
| -1 | -12,422,305 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 12,422,305.
Example:
1 x 12,422,305 = 12,422,305
and
-1 x -12,422,305 = 12,422,305
Notice both answers equal 12,422,305
With that explanation out of the way, let's continue. Next, we take the number 12,422,305 and divide it by 2:
12,422,305 ÷ 2 = 6,211,152.5
If the quotient is a whole number, then 2 and 6,211,152.5 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 | 12,422,305 | |
| -1 | -12,422,305 |
Now, we try dividing 12,422,305 by 3:
12,422,305 ÷ 3 = 4,140,768.3333
If the quotient is a whole number, then 3 and 4,140,768.3333 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 | 12,422,305 | |
| -1 | -12,422,305 |
Let's try dividing by 4:
12,422,305 ÷ 4 = 3,105,576.25
If the quotient is a whole number, then 4 and 3,105,576.25 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 | 12,422,305 | |
| -1 | 12,422,305 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 97 | 485 | 679 | 3,395 | 3,659 | 18,295 | 25,613 | 128,065 | 354,923 | 1,774,615 | 2,484,461 | 12,422,305 |
| -1 | -5 | -7 | -35 | -97 | -485 | -679 | -3,395 | -3,659 | -18,295 | -25,613 | -128,065 | -354,923 | -1,774,615 | -2,484,461 | -12,422,305 |
