LCM = 144

• Smallest 5 digit number is :- 10000

144 ) 10000 ( 69
9936
___________
64



The required number is :-
10000 + ( 144 - 64 )

10000 + 80

= 10080


So, 10080 is the smallest 5 digit number which is divisible by 12 , 16 and 18

Answer 2

heya dear

here is your answer !!

THE NUMBER WHICH IS DIVISIBLE BY 12 , 16 , 18 WILL BE LCM OF THE NUMBERS

LCM = 144

the smallest 5 digit number is 100000

=》 remainder = 64

so the required number is

10000 + (144 - 64)

10000 + 80

10080

so the smallest 5 digit number which is divisible by 12, 16, 18 is 10080

i hope it hel9s you
