Divisibility Rule of 6
Divisibility Rule of 6
Divisibility Rule of 6:
A number to be divisible by 6, it must also be divisible by 2 and 3.
Justification:
In case of a composite number we will consider the co-prime factors of a composite number.
We will then check the divisibility with each co-prime factor.
A number is divisible by a composite number, only when it is divisible by each co-prime factors of that number.
In case of 6 the co-prime factors are 2 and 3
So for a number to be divisible by 6, it must also be divisible by both 2 and 3. Therefore, we need to check if a number is even and then check if the sum of the digits is divisible by 3.

My experience with Abhyas academy is very good. I did not think that my every subject coming here will be so strong. The main thing is that the online tests had made me learn here more things.

8thWe started with lot of hope that Abhyas will help in better understnding of complex topics of highers classes. we are not disappointed with the progress our child has made after attending Abhyas. Though need to mention that we expected a lot more. On a scale of 1-10, we would give may be 7.
