of the following numbers are divisible by
2; by 4; by 8.
(ii) 2338
(iii) 43180 I (iv) 58334
(v) 65850
(vi) 35636
(i) 352​

Answer 1

Answer:

Divisibility test for 2- One place digit should be an even number(0,2,4,6,8)

Divisibility test for 4- Last two digits i.e. tens and ones place digit should be divisible by 4

Divisibility test for 8- Last 3 digits i.e. hundreds, tens and ones place digit should be divisible by 8

Step-by-step explanation:

i) 352-- As the ones digit is, it is divisible by 2.

     -- As the last 2 digits i.e. 52 is divisible by 4, the number is divisible by 4.

     -- As the last 3digits i.e. 352 is divisible by 8,the number is divisible by 4.

ii) 2338-- Divisible by 2

           -- Not Divisible by 4

           -- Not divisible by 8

iii) 43180-- Divisible by 2

           --  Divisible by 4

           -- Not divisible by 8

iv) 58334 --Divisible by 2

           --  Not Divisible by 4

           -- Not divisible by 8

v) 65850-- Divisible by 2

           --  Not Divisible by 4

           -- Not divisible by 8

vi) 35636-- Divisible by 2

           --  Divisible by 4

           -- Not divisible by 8
