Question

How many time is the LCM of 60 and 220 to that of of its HCF?

Answer 1

LCM is 60 it is answer for HCF

Answer 2

Answer:

33 times

Step-by-step explanation:

Given numbers,

60 and 220,

∵ 60 = 2 × 2 × 3 × 5

220 = 2 × 2 × 5 × 11,

Thus, HCF(60, 220) = 2 × 2 × 5 = 20, ( highest common factors )

Ans, LCM(60, 220) = 2 × 2 × 3 × 5 × 11 = 660,  ( least common multiple )

Now,

$\frac{660}{20}=33$

Hence, the LCM of 60 and 220 is 33 times of their HCF.
