Given : 47,815   and   2,37,405

To find : Check the divisibility of the given numbers by 3

Solution :

A given number is divisible by 3 iff sum of its digits is divisible by 3.

47,815

Sum of digit  = 4 + 7 + 8 + 1 + 5

= 25

25 is not divisible by 3

Hence 47,815 is not divisible by 3

2,37,405  

Sum of digits

= 2 + 3 + 7 + 4 + 0 + 5

= 21

21 is divisible by 3

Hence  2,37,405 is  divisible by 3
