Question

Find the LCM and HCF of 120 and 480

Answer 1

Answer:

lcm=480, hcf=120 is the right answer

Answer 2

Answer:

∴ LCM of $120$ and $480$ is $480$ and HCF is $120$.

Step-by-step explanation:

In context to question asked,

• We have to find LCM of $120$ and $480$.
• LCM is the least common factor.
• To find LCM, finding prime factorization of given numbers.
• Factors of $120 = 2*2*2*3*5$
• Factors of $480 = 2*2*2*2*2*3*5$

• Now,

  LCM of $120$ and $480$ = $2*2*2*2*2*3*5$

                               = $480$

• HCF is the highest common factor.
• To find HCF, find common multiples of given numbers.

 HCF of $120$ and $480$ = $2*2*2*3*5$

                              = $120$

• ∴ LCM of $120$ and $480$ is $480$ and HCF is $120$.
