Fid the LCM andHCF of 12 and 18 by prim e factorisation method​

Answer»

Answer:

36= LCM

6= HCF

Step-by-step explanation:

12 = 2 X 2 x 3

18 = 2 x 3 x 3

HCF = 2 x 3 = 6 There is only one 2 in 18 and only one 3 in 12.

LCM = 2 x 2 x 3 x 3 = 36 You need TWO 2’s and two 3’s to “cover” both 12 and 18.
