This question is from real numbers chapter in which we have given three numbers 17, 23 and 29 and we have been asked to find the HCF and LCM of the given numbers by using the method of prime factorization
RS Aggarwal, Class 10, chapter 1B, question no 2(iii)
17=17¹=17¹
23=23¹
29=29¹
From the above
HCF=1
LCM=17¹×23¹×29¹=11,339
