If you memorize the multiplication table up to 12x12, then you could recognize that 12x12=144, then you only have to factor each of the 12's is 3 x 2 x 2.
So 144 = 2 x 2 x 2 x 2 x 3 x 3. But if you don't know this, then: By inspection, it has 2 as a factor, then by sum of digits, it has 9 as a factor. Start by dividing the number by 2, until you are down to a number that cannot be divided by 2, then start dividing by 3 or 9, until you get to a number that is not divisible by 3 or 9, then see what you have left, and see if that number is prime. In this case, if you divide by 2, four times, then you are left with 9, which is 3 x 3.
