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, $$20 =2 \times 2 \times 3 \times 5$$
