How do you write 121 as a product of prime?
Well, isn't that just a happy little question! To write 121 as a product of prime numbers, we start by dividing it by the smallest prime number, which is 2. Since 121 is not divisible by 2, we move on to the next prime number, which is 3. After dividing 121 by 11, we get 11. And 11 is a prime number, so we have successfully written 121 as a product of prime numbers: 11 x 11. Happy little primes!
