Question

what is the divisibility rule of 2 3 4 5

Answer 1

A number is perfectly divisible by 2 when the dividend's last digit is an even number. Examples :-
12, 24, 36, 78, 100 every number is divisible hee because their last digit is 2, 4, 6, 8 and 0 which are even.
Whereas 11, 23, 59 these are not divisible because their last digit is not even.

For 3

A number is divisible by 3 if the sum of its all digits is divisible by 3. For example
81
Sum of digits = 8 + 1 = 9.
9 is divisible by 3, so 81 is also divisible.

73
Sum = 7 + 3 = 10
10 is not divisible by 3 so 73 is also not divisible


For 4:-
A number is divisible by 4, if last two digits are divisible by 4.
Example
124
Last two digits, 24
24 is divisible by 4 so 124 is also divisible.
623
Last two digits 23
23 is not divisible by 4 so 623 is also not divisible.



For 5
If the last digit is either 0 or 5 then it's divisible.
Examples
10
10 has 0 as last digit. So it's divisible by 5

25
25 has last digit 5 so it's divisible

78
78 has last digit as 8 so it's not divisible by 5.



Hope it helps dear friend ☺️✌️
