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 12,522,211, 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 | 12,522,211 | |
| -1 | -12,522,211 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 12,522,211.
Example:
1 x 12,522,211 = 12,522,211
and
-1 x -12,522,211 = 12,522,211
Notice both answers equal 12,522,211
With that explanation out of the way, let's continue. Next, we take the number 12,522,211 and divide it by 2:
12,522,211 ÷ 2 = 6,261,105.5
If the quotient is a whole number, then 2 and 6,261,105.5 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 | 12,522,211 | |
| -1 | -12,522,211 |
Now, we try dividing 12,522,211 by 3:
12,522,211 ÷ 3 = 4,174,070.3333
If the quotient is a whole number, then 3 and 4,174,070.3333 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 | 12,522,211 | |
| -1 | -12,522,211 |
Let's try dividing by 4:
12,522,211 ÷ 4 = 3,130,552.75
If the quotient is a whole number, then 4 and 3,130,552.75 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 | 12,522,211 | |
| -1 | 12,522,211 |
If you did it right, you will end up with this table:
| 1 | 13 | 79 | 89 | 137 | 1,027 | 1,157 | 1,781 | 7,031 | 10,823 | 12,193 | 91,403 | 140,699 | 158,509 | 963,247 | 12,522,211 |
| -1 | -13 | -79 | -89 | -137 | -1,027 | -1,157 | -1,781 | -7,031 | -10,823 | -12,193 | -91,403 | -140,699 | -158,509 | -963,247 | -12,522,211 |
