What Are LCM and HCF in Class 6 Maths Sainik School Exam?

First, let’s understand both terms.

LCM (Least Common Multiple): It is the smallest number that is a multiple of two or more numbers.
HCF (Highest Common Factor): It is the greatest number that divides two or more numbers exactly.

For example, the multiples of 4 are 4, 8, 12, 16, and 20. The multiples of 6 are 6, 12, 18, and 24. Therefore, the LCM of 4 and 6 is 12.

Similarly, the factors of 12 are 1, 2, 3, 4, 6, and 12. The factors of 18 are 1, 2, 3, 6, 9, and 18. So, the HCF of 12 and 18 is 6.
