A) 2520
B) 842
C) 2522
D) 840
Correct Answer: C
Solution :
LCM of 4, 5, 6, 7 and 8 \[=2\times 2\times 2\times 3\times 5\times 7=840\] Let required number be 840 K + 2 which is multiple of 13. Least value of K for which (840 K + 2) is divisible be 13 is K = 3 \[\therefore \]Required number \[=840\times 3+2=2520+2=2522\]You need to login to perform this action.
