Prime factorization of 9 = 3x3
Prime factorization of 21 = 3x7
Prime factorization of 35 = 5x7
3 is common in P.F. of both 9 and 21. 7 is common in P.F. of both 21 and 35.
L.C.M. = Multiplication of common numbers x Multiplication of uncommon numbers L.C.M. = 3x7(common numbers) x 3x5(uncommon numbers) = 21x15 = 315
