Basic Techniques for carrying out Divisibility Test of Numbers
How to check if a number can be divided by 2?
Sol: A number is divisible by 2 if its last digit is divisible by 2. Simply said, this means if last digit of a number is 0, 2, 4, 6 or 8, the number will be fully divided by 2
For Example : 8, 36, 296, 123899994 all are divisible by 2
How to check if a number can be divided by 3?
Sol : A number is divisible by 3 if the sum of its digits is divisible by 3
For Example : In case of 59892, the sum of its digit will be 5 + 9 + 8 + 9 + 2 = 33 and since 33 is divisible by 3 therefore this number will be divided fully by 3
