Detailed Solution

L.C.M. of 25, 30, 35 and 40

Let us find LCM by prime factorisation.

Prime factorisation of 25 = 5 x 5 = 52

Prime factorisation of 30 = 2 x 3 x 5 

Prime factorisation of 35 = 5 x 7

Prime factorisation of 40 = 2 x 2 x 2 x 5 = 23 x 5

Thus, 

LCM (25, 30, 35, 40) = 2 x 2 x 2 x 3 x 5 x 5 x 7 =  4200
