Question

Find the smallest number which when added to 5 is exactly divisible by 12 16 and 18

Answer 1

Answer:

Step-by-step explanation:

factors of 12,16 and 18 are

12=2*2*3

16=2^2

18=2*3*3

LCM(12,16,18)=2^4*3^2=16*9=144

144-5=139

hence 139 must be added to get 144 which is exactly divisible by 12,16

and 18
