What are HCF and LCM in Algebra?

Highest Common Factor (HCF) in Algebra

The highest common factor (HCF), also known as the greatest common divisor (GCD), is the largest factor common to two or more algebraic expressions. When working with algebra, finding the HCF involves factoring the expressions and identifying the terms shared by all expressions.

For example:
Find the HCF of 6x²y and 9xy².

Steps:

1. Factorize each term:
   • 6x²y=2⋅3⋅x⋅x⋅y
   • 9xy²=3⋅3⋅x⋅y⋅y
2. Identify common factors:
   • Common terms: 3⋅x⋅y
3. HCF = 3xy.

Least Common Multiple (LCM) in Algebra

The least common multiple (LCM) is the smallest expression that is a multiple of two or more algebraic expressions. It involves combining the highest powers of all factors present in the given expressions.

For example:
Find the LCM of 6x²y and 9xy².

Steps:

1. Factorize each term:
   • 6x²y=2⋅3⋅x⋅x⋅y
   • 9xy²=3⋅3⋅x⋅y⋅y
2. Take the highest powers of all factors:
   • From 6x²y and 9xy², the factors are 2, 3, x², y².
3. LCM = 2.3.3.x².y² = 18x²y².
