Question

1. Using prime factorisation, find the HCF and LCM of:
(1) 36,84. [2] 23, 31
(iii) 96, 404
(iv) 144, 198 (v) 396, 1080 (vi) 1152, 1664
In each case, verify that:
HCF × LCM = product of given numbers.​

Answer 1

Answer:

(i) HCF= 12, LCM= 252, (ii) HCF= 1, LCM= 713 <br> (iii) HCF = 4, LCM= 9696, (iv) HCF = 18, LCM= 1548 <br> (v) HCF= 36, LCM= 11880, (iv) HCF = 18, LCM= 14976
