Divisibility by 12





In this topic divisibility by 12 first let us see the definition. All the numbers which are divisible by 3 and divisible by 4 are divisible by 12.

Example 1:

Check 8520 is divisible by 12 or not.
To check any number is divisible by 12 or not first we have to try the following steps:

1. We have to check whether the given number is divisible by 3.

2. Then we have to check whether the given number is divisible by 4.

If the given number is satisfying those conditions we can decide that the given number is divisible by 12.Otherwise we can say that the given number is not divisible by 12. Here the given number is 8520.According to the procedure first let us check the given number is divisible by 3.For that we have to calculate the sum of the digits that is 8 + 5 + 2 + 0 = 15





So it is divisible by 3.To check whether 8520 is divisible by 4 we need to consider the last two digits that is 20





So it is divisible by 4.Therefore we can say the given number 8520 is divisible by 12.

In the following worksheet you can find 5 questions in the form of quiz and you can get direct answers too.


Example 2:

Check 9110 is divisible by 12 or not.
To check any number is divisible by 12 or not first we have to try the following steps:

1. We have to check whether the given number is divisible by 3.

2. Then we have to check whether the given number is divisible by 4.

If the given number is satisfying those conditions we can decide that the given number is divisible by 12.Otherwise we can say that the given number is not divisible by 12.

Here the given number is 9110.According to the procedure first let us check the given number is divisible by 3.For that we have to calculate the sum of the digits that is 9 + 1 + 1 + 0 = 11

Here the given number is not divisible by 3.So we can say the given number is not divisible by 12.
