To check if a number is divisible by 2,3, 4, 6, 8, 9, we would use divisibility tests:
(A) 2 {The number 123456 is definitely divisible by 2 as it is an even number}
(B) 3 {The number 123456 is definitely divisible by 3 as the sum of the digits of the number 123456 is 21 which is divisible by 3 thus satisfying the divisibility condition for 3}
(C) 4 {The number 123456 is definitely divisible by 4 as the number formed by last two digits of the number 123456 is 56 which is divisible by 4 thus satisfying the divisibility condition for 4}
(D) 6 {The number 123456 is definitely divisible by 6 as the number 123456 is divisible by both 2 and 3 thus satisfying the divisibility condition for 6}
(E) 8 {The number 123456 is definitely divisible by 8 as the number formed by last three digits of the number 123456 is 456 which is divisible by 8 thus satisfying the divisibility condition for 8}
(F) 9 {The number 123456 is not divisible by 9 as the sum of the digits of the number 123456 is 21 which is not divisible by 9 thus not satisfying the divisibility condition for 9}
Ans. (A, B, C, D, E)
