Correct Answer: 365


Solution : Prime factorization of 8, 10, 12, and 18:
8 = 2 3
10 = 2 × 5
12 = 2 2 × 3
18 = 2 × 3 2
So, the LCM of 8, 10, 12, and 18 = 2 3 × 3 2 × 5 = 360.
The least number which when divided by 8, 10, 12, and 18 leaves a remainder of 5 in each case
= 360 + 5 = 365.
Hence, the correct answer is 365.
