Find the LCM and HCF of the following integers by applying the prime factorization method: (1) 12, 15 and 21 (2) 17, 23 and 29 (3) 8, 9 and 25

Find the LCM and HCF of the following integers by applying the prime f

1.	Find the LCM and HCF of the following integers by applying the prime factorization method: (1) 12, 15 and 21 (2) 17, 23 and 29 (3) 8, 9 and 25
Answer» (1) LCM(12, 15, 21) = 420, HCF(12, 15, 21) = 3 (2) LCM(17, 23, 29) = 11339, HCF(17, 23, 29) = 1 (3) LCM(8, 9, 25) = 1800, HCF(8, 9, 25) = 1. Thelargest possible number which divides the given numbers exactly without any remainder is calledthehighest common factorof the given numbers.
