😎Hey everyone! Today we're going to explore two important math concepts: LCM (Least Common Multiple) and HCF (Highest Common Factor). These concepts are crucial for solving math problems and are used in various real-life applications.

What is LCM?

The Least Common Multiple (LCM) of two or more numbers is the smallest number that is a multiple of each of the given numbers. In other words, it's the smallest number that all the given numbers can divide into evenly.

Example: Find the LCM of 4 and 6.

Multiples of 4: 4, 8, 12, 16, 20, ...
Multiples of 6: 6, 12, 18, 24, 30, ...

The smallest number that appears in both lists is 12, so the LCM of 4 and 6 is 12.

What is HCF?

The Highest Common Factor (HCF) of two or more numbers is the largest number that divides each of the given numbers without leaving a remainder. In other words, it's the largest number that is a factor of each of the given numbers.

Example: Find the HCF of 12 and 18.

Factors of 12: 1, 2, 3, 4, 6, 12
Factors of 18: 1, 2, 3, 6, 9, 18

The largest number that appears in both lists is 6, so the HCF of 12 and 18 is 6.

Why are LCM and HCF Important?

They're used in various math problems, such as adding and subtracting fractions.
They're essential for solving problems involving ratios and proportions.
They're used in real-life applications, such as music, architecture, and engineering.
