Answer 1

Here is your answer dear⤵️⤵️


First we will find the LCM of 12, 15, 20, 54

12 = 2×2×3

15 = 5×3

20 = 5×2×2

54 = 2×3×3×3

Common factors => There is no common factor so let the common factors be 1

LCM of 12, 15, 20, 54 = 2×2×3×5×3×5×2×2×2×3×3×3

= 540


So to find the least number = 540 + 8 = 548
