Fine the L.C.M. of 18,24 and 32.
Since as we know that lowest common multiple are the least multiples that are also common between numbers.
Multiples of 18=18,36,54,72,.........,288......
Multiples of 24=24,48,72,........,288,.......
Multiples of 32=32,64,96,...........................,288,........
Hence, L.C.M. of 18,24 and 32 is 288.
