**HCF in case of only two numbers:**

- Suppose the question asks to calculate the HCF of any two numbers. Then Divide the larger number by the smaller one.
- Now divide the divisor by the remainder.
- Keep dividing the preceding divisor with the remainder until a Zero remainder is obtained.
- The last divisor obtained will be the HCF of those two given number.

**HCF in case of more than two numbers:**

- The HCF of these two numbers and the third number will be the HCF of all three numbers and so forth.
- Choose any two numbers and find their HCF by applying the above-mentioned method.

**The rule for Solving HCF and LCM Questions and Answers:**
