If the LCM of $\mathrm{f}(\mathrm{x})$ and $\mathrm{g}(\mathrm{x})$ is $\mathrm{a}^{6}-\mathrm{b}^{6}$, then their $\mathrm{HCF}$ can be
(1) $a-b$
(2) $a^{2}+a b+b^{2}$
(3) $a^{2}-a b+b^{2}$
(4) All of these

Key Concepts

Polynomial Factorization

This key concept involves expressing a polynomial as a product of its irreducible factors. Understanding how to break down a complex polynomial into simpler factors is essential for solving equations, simplifying expressions, and analyzing divisibility properties. Factorization techniques are central in many areas of algebra and help identify common factors between polynomials.

Greatest Common Divisor (GCD) and Least Common Multiple (LCM) in Polynomials

The notion of GCD (or HCF) and LCM for polynomials mirrors that in the integers. The GCD of two polynomials is the highest degree polynomial that divides both without remainder, while the LCM is the lowest degree polynomial that both can divide into without remainder. These concepts are interrelated and are used for solving polynomial equations, simplifying rational expressions, and analyzing the structure of polynomial factorization.

Difference of Powers Factorization

This is a specific algebraic identity that allows one to factor expressions of the form a^n - b^n. Special cases include the difference of squares (n=2) and the difference of cubes (n=3), but general formulas exist for higher exponents. Applying the difference of powers identity is crucial in breaking down expressions like a^6 - b^6 into simpler, factorable components, which in turn assists in determining the common factors among related polynomials.
