Question

Find the HCF and LCM of 72 and 120, using the prime factorisation method.​

Answer 1

Answer:

From the above three equations, we can see that the common factors of 6, 72, and 120 is 2×3=6. So, we get the highest common factor or HCF of 6, 72, and 120 as 6. Hence, the LCM of the three numbers is 360.
