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 12,300,101, 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 | 12,300,101 | |
| -1 | -12,300,101 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 12,300,101.
Example:
1 x 12,300,101 = 12,300,101
and
-1 x -12,300,101 = 12,300,101
Notice both answers equal 12,300,101
With that explanation out of the way, let's continue. Next, we take the number 12,300,101 and divide it by 2:
12,300,101 ÷ 2 = 6,150,050.5
If the quotient is a whole number, then 2 and 6,150,050.5 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 | 12,300,101 | |
| -1 | -12,300,101 |
Now, we try dividing 12,300,101 by 3:
12,300,101 ÷ 3 = 4,100,033.6667
If the quotient is a whole number, then 3 and 4,100,033.6667 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 | 12,300,101 | |
| -1 | -12,300,101 |
Let's try dividing by 4:
12,300,101 ÷ 4 = 3,075,025.25
If the quotient is a whole number, then 4 and 3,075,025.25 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 | 12,300,101 | |
| -1 | 12,300,101 |
If you did it right, you will end up with this table:
| 1 | 11 | 23 | 61 | 253 | 671 | 797 | 1,403 | 8,767 | 15,433 | 18,331 | 48,617 | 201,641 | 534,787 | 1,118,191 | 12,300,101 |
| -1 | -11 | -23 | -61 | -253 | -671 | -797 | -1,403 | -8,767 | -15,433 | -18,331 | -48,617 | -201,641 | -534,787 | -1,118,191 | -12,300,101 |
