Question

a)8136 b)9123 c)8727 d)9383

Answer 1

Answer: 9383

Step-by-step explanation:

First we need to find the LCM of 12, 14, 21, 33 and 54

12=2x2x3

14=2x7

21=3x7

33=3x11

54=2x3x3x3

So LCM= 2x2x3x7x11x3x3 =8316

So the required number should be divisible by 8316.

8316x2=16632

16632-7249=9383
