A) 420
B) 840
C) 2470
D) 2522
Correct Answer: D
Solution :
\[4={{2}^{2}}\] \[6=2\times 3\] \[7=7\] \[10=2\times 5\] \[LCM=4\times 3\times 7\times 5=420\] Number \[=420k+2\] \[=416k+(4k+2)\] When \[k=6,\] then \[4k+2\] \[=4\times 6+2=26\] which is divisible by 13. \[\therefore \] Required number \[=420k+2\] \[=420\times 6+2=2522\]You need to login to perform this action.
