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 12,274,285, 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 | 12,274,285 | |
| -1 | -12,274,285 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 12,274,285.
Example:
1 x 12,274,285 = 12,274,285
and
-1 x -12,274,285 = 12,274,285
Notice both answers equal 12,274,285
With that explanation out of the way, let's continue. Next, we take the number 12,274,285 and divide it by 2:
12,274,285 ÷ 2 = 6,137,142.5
If the quotient is a whole number, then 2 and 6,137,142.5 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 | 12,274,285 | |
| -1 | -12,274,285 |
Now, we try dividing 12,274,285 by 3:
12,274,285 ÷ 3 = 4,091,428.3333
If the quotient is a whole number, then 3 and 4,091,428.3333 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 | 12,274,285 | |
| -1 | -12,274,285 |
Let's try dividing by 4:
12,274,285 ÷ 4 = 3,068,571.25
If the quotient is a whole number, then 4 and 3,068,571.25 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 | 12,274,285 | |
| -1 | 12,274,285 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 47 | 95 | 235 | 893 | 2,749 | 4,465 | 13,745 | 52,231 | 129,203 | 261,155 | 646,015 | 2,454,857 | 12,274,285 |
| -1 | -5 | -19 | -47 | -95 | -235 | -893 | -2,749 | -4,465 | -13,745 | -52,231 | -129,203 | -261,155 | -646,015 | -2,454,857 | -12,274,285 |
