Answer 2

Answer:

A simple method is as follows:

Biggest number is 18

18×2=36, 36is divisible by 4 but not 16

18×3=54=54 is divisible by 4buy not 16

go on in the same way

18×8=144, 144 is divisible by 4 and 16

So LCM=144

Another method is as follows

4, 8,12,16,20,24,28,32, 36, more such numbers,126,144

16=32,48, some more such numbers,128,144

18,36,54,72,90,108,126,144

So 145 is LCM

Another method is as follows

4=2×2

16=2×2×2×2

18=2×3×3

LCM= 2(common to all)×2(common to two numbers)×2×2×3×3(remaining numbers)

=2×2×2×2×3×3=144
