The LCM and ratio of three numbers are 1386 and 3 : 7 : 11, respectively. The sum of the greatest and least numbers is: |
60 64 84 108 |
84 |
The ratio of three numbers = 3 : 7 : 11 The LCM = 1386 3x × 7x × 11x = 1386 x = \(\frac{1386}{3 × 7 × 11}\) = 6 The sum of the greatest and least numbers is = 3x + 11x = 14x = 14 × 6 = 84 |
