## What is the ratio between HCF and LCM of 12 and 18?

Factors of 18 1, 2, 3, 6, 9 and 18. Therefore, common factor of 12 and 18 **1, 2, 3 and 6. Highest common factor (H.C.F) of 12 and 18 6 [since 6 is the highest common factor].**

## What is a HCF of 18?

The HCF of 18 and 48 is **6. To calculate the HCF (Highest Common Factor) of 18 and 48, we need to factor each number (factors of 18 1, 2, 3, 6, 9, 18; factors of 48 1, 2, 3, 4, 6, 8, 12, 16, 24, 48) and choose the highest factor that exactly divides both 18 and 48, i.e., 6.**

## What is HCF and LCM of 12 and 18?

Therefore, the HCF of 12 and 18 is **6. Example 3: Find the HCF of 12 and 18, if their LCM is 36. Therefore, the highest common factor of 12 and 18 is 6.**
