This theorem also says that the prime factorisation of a natural number is unique, except for the order of its factors. We will find the prime factorizations of $$126, 162$$ and $$180$$. Check out how CUEMATH Teachers will explain The Fundamental Theorem of Arithmetic to your kid using interactive simulations & worksheets so they never have to memorise anything in Math again! 1 Class 10 Maths Exercise 1.2 Solutions. Fundamental Theorem of Arithmetic: Every composite number can be expressed (factorised ) as a product of primes, and this factorisation is unique, apart from the order in which the prime factors occur. 1) Statements After Reviewing Work Done Earlier. $\text{LCM }(48, 72) = 2^4 \times 3^2 = 144$. Suppose they both start at the same point and at the same time, and go in the same direction. For example 20 can be expressed as 2xx2xx5.
