Write the number 20 as a product of prime factors.

Answer 1

To find the prime factorization of a number, we need to express it as a product of its prime factors.

To find the prime factors of 20, we start with the smallest prime number, which is 2. We divide 20 by 2 to get 10.

Next, we continue dividing the result (10) by the smallest prime number, 2, until we cannot divide any further. We divide 10 by 2 again to get 5.

Since 5 is a prime number, we have found all the prime factors. Therefore, the prime factorization of 20 is 2 x 2 x 5, which can also be written as 2^2 x 5.
