What does the Fundamental Theorem of Arithmetic state?
AEvery natural number is prime
BEvery natural number has exactly two factors
CEvery composite number has a unique prime factorisation, apart from the order of factors
DEvery even number is a multiple of 4
Answer & Solution
Correct answer: C. Every composite number has a unique prime factorisation, apart from the order of factors
The theorem says that each natural number greater than 1 can be expressed as a product of primes, and this factorisation is unique except for the order in which the prime factors are written.
