Question

Find the HCF and LCM of the 12 and 18 by the prime factorization method. ​

Answer 1

Step-by-step explanation:

12 = 2x2x3

18 = 2x3x3

Lcm = 2²x3² = 4x9 = 36

HCF = 2x3 = 6

Answer 2

HCF =

Common factor of 12=1,2,3,6

Common factor of 18= 1,2,3,6,9,18

HCF of 12 and 18 is 6

LCM=

Multiples of 12 =12 ,24,36,48,60,72,84 ............

Multiples of 18 = 18,36,54.........................................

LCM of 12 and 18is 36
