Solution :
i) 26 and 91
26=2×13×1(expressing as product of it’s prime factors)
91=7×13×1(expressing as product of it’s prime factors)
So, LCM(26,91)=2×7×13×1=182
HCF(26,91)=13×1=13
Verification:
LCM×HCF=13×182=2366
Product of 26 and 91 =2366
Therefore,LCM×HCF=Product of the two numbers .
i) 510 and...
Solution :
i) 12,15 and 21
12=2×2×3
15=5×3
21=7×3
From the above ,HCF(12,15,21)=3and LCM(12,15,21)=420
ii)17,23,and 29
17=17×1
23=23×1
29=29×1
From the above ,HCF(17,23,29)=1and LCM(17,23,29)=11339
iii)8,9 and 25
8=2×2×2
9=3×3
25=5×5
From the above ,HCF(8,9,25)=1and LCM(8,9,25)=1800
General integers are 408 and 1032 where 408 < 1032
By applying Euclid’s division lemma, we get
1032 = 408 × 2 + 216
Since remainder ≠ 0, apply division lemma on division...
