If two positive integers p and q can be expressed as p = ab² and q = a³b where a and b are prime numbers, then the LCM (p, q) is:

Prime numbers are natural numbers greater than one that have exactly two factors which are one and themselves. They cannot be divided evenly by any other numbers. Examples include two five seven and eleven. Prime numbers are fundamental in mathematics and cryptography because of their unique properties and distribution patterns.

Chapter one of Class ten Mathematics covers Real Numbers for the CBSE Exam 2024-25. It includes important concepts like Euclid’s division lemma, the Fundamental Theorem of Arithmetic and the properties of rational and irrational numbers. This chapter helps in understanding divisibility rules, HCF and LCM and the decimal expansion of different numbers with logical reasoning.
