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 12,362,245, 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 | 12,362,245 | |
| -1 | -12,362,245 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 12,362,245.
Example:
1 x 12,362,245 = 12,362,245
and
-1 x -12,362,245 = 12,362,245
Notice both answers equal 12,362,245
With that explanation out of the way, let's continue. Next, we take the number 12,362,245 and divide it by 2:
12,362,245 ÷ 2 = 6,181,122.5
If the quotient is a whole number, then 2 and 6,181,122.5 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 | 12,362,245 | |
| -1 | -12,362,245 |
Now, we try dividing 12,362,245 by 3:
12,362,245 ÷ 3 = 4,120,748.3333
If the quotient is a whole number, then 3 and 4,120,748.3333 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 | 12,362,245 | |
| -1 | -12,362,245 |
Let's try dividing by 4:
12,362,245 ÷ 4 = 3,090,561.25
If the quotient is a whole number, then 4 and 3,090,561.25 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 | 12,362,245 | |
| -1 | 12,362,245 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 107 | 535 | 749 | 3,301 | 3,745 | 16,505 | 23,107 | 115,535 | 353,207 | 1,766,035 | 2,472,449 | 12,362,245 |
| -1 | -5 | -7 | -35 | -107 | -535 | -749 | -3,301 | -3,745 | -16,505 | -23,107 | -115,535 | -353,207 | -1,766,035 | -2,472,449 | -12,362,245 |
