Find the LCM and HCF of the following integers by applying the prime factorisation method. (ii) 17, 23 and 29
(ii) 17, 23 and 29 
Now, 17 = 1 × 17, 23 = 1 × 23, 29 = 1 × 29
Here, 1 is the smallest common factor.
∴ H.C.F. (17, 23, 29)= 1
And 171, 231 and 291 are the greatest powers of prime factors.
∴ L.C.M. (17, 23, 29) = 17 × 23 × 29 = 11339.
Express each number as a product of its prime factors: (iv) 5005
Express each number as a product of its prime factors: (v) 7429
