Question

7.Find the LCM and HCF of 6 and 20 by the prime factorisation method.​

Answer 1

Answer:

the lcm of 60and 20 is = 60

Step-by-step explanation:

LCM=

2 | 6,20

2 | 3,10

3 | 3,5

5 | 1,5

  | 1,1

2*2*3*5 = 60

Answer 2

Answer:

L.C.M. of 6 and 20 = 2×2×3×5 = 60.

H.C.F. of 6 = 2×3 = 6

H.C.F. of 20 = 2×2×5 = 20
