Question

The fundamental theorem of arithmetic is applicable to 

A) 4 

B) 3 

C) 2 

D) 1

Answer 1

Correct option is (A) 4

The fundamental theorem of arithmetic states that every composite number can be factorized as a product of primes and this factorization is unique, apart from the order in which the prime factors occurs.

It means fundamental theorem of arithmetic is applicable to composite numbers and among given numbers only 4 is a composite number.

Thus, the fundamental theorem of arithmetic is applicable to 4.
