Question
Find the LCM and HCF of the following integers by applying the prime factorisation method.
17, 23 and 29
Advertisements
Solution
17, 23 and 29
Let us first find the factors of 17, 23 and 29
17 = 1 × 17
23 = 1 × 23
29 = 1 × 29
L.C.M. of 17, 23 and 29 = 1 × 17 × 23 × 29
L.C.M. of 17, 23 and 29 = 11339
H.C.F. of 17, 23 and 29 = 1
