A) 34
B) 55
C) 17
D) None of these
Correct Answer: D
Solution :
Sol. [d] The required greatest number is HCF of \[(230-5),\] \[(1314-5)\]and \[(1331-5)\] i.e., 225, 1309 and 1326. |
\[225=3\times 3\times 5\times 5={{3}^{2}}\times {{5}^{2}}\] |
\[1309=7\times 11\times 17\] |
and \[1326=2\times 3\times 13\times 17\] |
\[\therefore \,\,\,\,\,HCF\,\,(225,1309,1326)=1\] |
