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 12,052,645, 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 | 12,052,645 | |
| -1 | -12,052,645 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 12,052,645.
Example:
1 x 12,052,645 = 12,052,645
and
-1 x -12,052,645 = 12,052,645
Notice both answers equal 12,052,645
With that explanation out of the way, let's continue. Next, we take the number 12,052,645 and divide it by 2:
12,052,645 ÷ 2 = 6,026,322.5
If the quotient is a whole number, then 2 and 6,026,322.5 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 | 12,052,645 | |
| -1 | -12,052,645 |
Now, we try dividing 12,052,645 by 3:
12,052,645 ÷ 3 = 4,017,548.3333
If the quotient is a whole number, then 3 and 4,017,548.3333 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 | 12,052,645 | |
| -1 | -12,052,645 |
Let's try dividing by 4:
12,052,645 ÷ 4 = 3,013,161.25
If the quotient is a whole number, then 4 and 3,013,161.25 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 | 12,052,645 | |
| -1 | 12,052,645 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 31 | 55 | 155 | 341 | 1,705 | 7,069 | 35,345 | 77,759 | 219,139 | 388,795 | 1,095,695 | 2,410,529 | 12,052,645 |
| -1 | -5 | -11 | -31 | -55 | -155 | -341 | -1,705 | -7,069 | -35,345 | -77,759 | -219,139 | -388,795 | -1,095,695 | -2,410,529 | -12,052,645 |
