Question

if a number is divisible by 8 then it is divisible by 4 and 2 also write the reason​

Answer 1

Answer:

No. The number 12 is divisible by both 2 and 4 but is not divisible by 8. Also 20, 28, and all the other numbers = 4(2n+1) for n = 0 to infinity.

Answer 2

Answer:

yes it is very correct

here it happens because 4 and 2 are the factors of 8.

if a number x is divisible with a number y , then x will be also divisible with the factors of y .

for eg , consider 72 .

72 is divisible by 36 .

then 72 is also divisibl by the factors of 36 ===> 2 , 18 , 3 , 12 , 4 , 9 , 6

you can divide if you have any of further doubt

warning : first you should check whether the number is divisible by 8 or not .

in the above answer she hadn't checked that first .

if 12 was divisible by 8 then definitely it will be divisible by 2 and 4.
