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 12,364,555, 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 | 12,364,555 | |
| -1 | -12,364,555 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 12,364,555.
Example:
1 x 12,364,555 = 12,364,555
and
-1 x -12,364,555 = 12,364,555
Notice both answers equal 12,364,555
With that explanation out of the way, let's continue. Next, we take the number 12,364,555 and divide it by 2:
12,364,555 ÷ 2 = 6,182,277.5
If the quotient is a whole number, then 2 and 6,182,277.5 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 | 12,364,555 | |
| -1 | -12,364,555 |
Now, we try dividing 12,364,555 by 3:
12,364,555 ÷ 3 = 4,121,518.3333
If the quotient is a whole number, then 3 and 4,121,518.3333 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 | 12,364,555 | |
| -1 | -12,364,555 |
Let's try dividing by 4:
12,364,555 ÷ 4 = 3,091,138.75
If the quotient is a whole number, then 4 and 3,091,138.75 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 | 12,364,555 | |
| -1 | 12,364,555 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 541 | 653 | 2,705 | 3,265 | 3,787 | 4,571 | 18,935 | 22,855 | 353,273 | 1,766,365 | 2,472,911 | 12,364,555 |
| -1 | -5 | -7 | -35 | -541 | -653 | -2,705 | -3,265 | -3,787 | -4,571 | -18,935 | -22,855 | -353,273 | -1,766,365 | -2,472,911 | -12,364,555 |
