Question

47. (The smallest common multiple of 30, 45 and 60
between 200 and 400) = (The largest common factor of
15, 24 and 45) is equal to​

Answer 1

Answer:

L.C.M(30,45,60) :

30 = 2*3*5

45 = 3*3*5

60 = 2*2*3*5

L.C.M = 2*2 x 3*3 x 5 = 4*9*5 = 180

H.C.F(15,24,45) :

15 = 3*5

24 = 3*2*2*2

45 = 3*3*5

As only common factor is 3,

H.C.F = 3
