A) 500
B) 1800
C) 1810
D) 1500
Correct Answer: B
Solution :
Sol. [b] We have, \[8=2\times 2\times 2,\] |
\[9=3\times 3,\,25=5\times 5\] |
\[HCF(8,9,25)=1\]and |
\[LCM(8,9,25)={{2}^{3}}\times {{3}^{2}}\times {{5}^{2}}=1800\] |
\[\therefore \,\,\,\,\,\,HCF(8,9,25)\times LCM(8,9,25)=1\times 1800=1800\] |
