If a=23×34×72and b=23×32×53, then which of the following is true?
HCF = Product of the smallest powers of each common prime factor in the numbers.
LCM = Product of the largest powers of each common prime factor in the numbers.
The common prime factors of a and b are 2 and 3.
Thus, HCF=23×32.
All the prime factors of a and b are 2,3,5 and 7.
Thus, LCM=23×34×53×72
