Find the H.C.F and L.C.M of 18 and 24 by prime factorisation method |
|
Answer» factors of 18 = 2x3x3 24 = 2x2x2x3common factors in both are 2 and 3 onlythus HCF = 2x3 = 6please check your answer divide 18 by 6 the remainder is zero 24 by 6 the remainder is zero if we have to do the LCM and HCF of this by prime factorization we have to divide these two numbers by a number which they are both diesel divisible if we divide this number by 2 we get 9 and 12 after this wedding this by 3 week at 3 and 4 again 3 and we get 1 and 4 and the four finally we get the answer one that the LCM of these two numbers is 2 x 3 multiply 3 and again by 4 18=2×3×324=2×2×2×3Common factor=2×3Hcf=6 |
