Question

find least number which should be added to 2497 so sum is exactly divisible by 2,4,5,6. answer 23

Answer 1

answer is 23 
if 2497+ x is exactly divisible by 2,4,5,6
it should be divisible with lcm of 2,4,5,6
lcm 2,4,5,6=60
multiples of 60 nearest to  2497 = 2460,2520
so 2520 is divisible by 2,4,5,6
x=2520-2497
  =23

Answer 2

if 2497+ x is divisible by 2,4,5,6
it should be divisible with lcm of 2,4,5,6
lcm 2,4,5,6 = 60
multiples of 60 nearest 2497 = 2460,2520
so 2497 is divisible by 2,4,5,6
x= 2520-2497
