Answer 1

Question :-

Minimum four digit number divisible by 18,16,24

Answer:-

L.C.M of 18,16,24 -

18 = 2 x 3 x 3

16 = 2 x 2 x 2 x 2

24 = 2 x 2 x 2 x 3

L.C.M = 2 x 2 x 2 x 2 x 3 x 3 = 144.

But 144 is a 3 digit number. So we must see the first four digit multiple of 144.

→ 144 x 7 = 1008.

∴ 1008 is the first four digit number divisible by 18, 16 & 24.
