Divisibility by 6:

How do you know that a number is divisible by 6? Well, a number is divisible by 6 if it is both divisible by 2 and 3. In short, an even number that is divisible by 3.

Example 1:


The first thing that we need to do is to inspect the given number if it is divisible by 6 or not. 

Since the given number is not an even number and besides, the sum of the digits is not a multiple of 3 as shown below





then the given number is not divisible by 6. There's a remainder of 1 in the division. The answer or a quotient must be a whole number itself. You should not have a fraction or a remainder in the final answer. 

Example 2:


The first thing that we need to do is to inspect the given number if it is divisible by 6 or not. 

Since the given number is not an even number but the sum of the digits is a multiple of 3 as shown below

  


 
then the given number is not divisible by 6. There's a remainder of 3 in the division. The answer or a quotient must be a whole number itself. You should not have a fraction or a remainder in the final answer. 

Example 3:


The first thing that we need to do is to inspect the given number if it is divisible by 6 or not. 

Although the given number is an even number but the sum of the digits is not a multiple of 3 as shown below





then the given number is not divisible by 6. There's a remainder of 4 in the division. The answer or a quotient must be a whole number itself. You should not have a fraction or a remainder in the final answer. 

Example 4:


The first thing that we need to do is to inspect the given number if it is divisible by 6 or not. 

Since the given number is an even number and the sum of the digits is a multiple of 3 as shown below





then the given number is divisible by 6. There's no remainder or a fraction in the division.

You should consider in studying the divisibility of a number because you will use these principles later when you will study higher Math subjects that involves the division of a number, simplifying fractions, and even factoring. 

This method can also be used for negative integers as long as the given number is both divisible by 2 and 3. Again, there should be no remainder or a fraction in the division.
