Fundamental Theorem of Arithmetic:Every composite number can be expressed (factorised) a product of primes and this factorisation is unique, apart from the order in which the prime factors occur.
In previous classes you have studied that natural number can be written as a product of its prime factors.
Fundamental Theorem of Arithmetic says that every composite number can be factorized as a product of Prime Numbers in a unique way except the order in which the prime number occurs.
In this exercise we also find HCF and LCM which you have learnt in earlier classes.
HCF = product of the smallest power of each common prime factor in the number.
LCM= product of the greater power of each prime factor involved in the number.
We also find LCM and HCF by using property
LCM × HCF = Product of two numbers
