Check whether 876 and 345 are divisible by 3? Also check whether 3 divides the difference of 876 and 345?

Given, “876” and “345” two numbers.

Need to find out they are divisible by 3 and also their difference divides 3 should be found out.

⇒ sum of the digits of 876 is 8 + 7 + 6 = 21 is divisible by 3.

⇒ sum of the digits of 345 is 3 + 4 + 5 = 12 is divisible by 3.

⇒ difference of 876 and 345 = 876 -345 = 531

⇒ Sum of the digits of 531 = 5 + 3 + 1 = 9 is divisible by 3.

Hence, 876 and 345 are divisible by 3 and the difference between them is also divisible by 3.
