Question

Find the smallest number which when added to 5 is exactly divisible by 12,14 and 18. Pls answer fast

Answer 1

Answer:

Smallest number = 247

Step-by-step explanation:

Smallest number added to x exactly divisibe by a, b, c is

$= lcm \: of \: (a, b, c) - x$

let 12, 14, 18 be a, b, c respectively

And x = 5

12 = 2 * 2 * 3

14= 7 * 2

18 = 3 * 3 * 2

LCM of 12, 14, 18 = 9 * 4 * 7=252

Smallest Number = 252 - 5 = 247
