Step 1

Prime numbers are those numbers whose only multiples are 1 and the number itself.

Prime factorization is basically a process to find which prime numbers can be multiplied to get the original number.

Step 2

1. Factors of 20 are 1,2,4,5,10 and 20

Hence, prime factorization of 20 is, \(20 =2 \times 2 \times 5\)

2. Factors of 36 are 1,2,3,4,6,9,12,18,36.

Hence, prime factorization of 36 is, \(36 =2 \times 2 \times 3 \times 3\)

3. Factors of 28 are 1,2,4,7,14,28.

Hence, prime factorization of 28 is, \(28 =2 \times 2 \times 7\)

4. Factors of 60 are 1,2,3,4,5,6,10,12,15,20,30,60.

Hence, prime factorization of 60 is, \(20 =2 \times 2 \times 3 \times 5\)
