Question

find the l.c.m and H.c.f of the following integers by applying prime factorisation method 12;23;29​

Answer 1

Answer:

Prime factorization of 12 is 2 x 2 x 3

Prime factorization of 23 is 1 x 23

Prime factorization of 29 is 1 x 29

for LCM we need to multiply all the numbers

Therefore LCM = 2 x 2 x 3 x 23 x 29 = 8004

and HCF = 1 because they don't have any common factor
