Question

check the divisibility of 2166564 by 9 and 4​

Answer 1

Answer:

Divisibility rule of 9 :

if sum of digits is divisible by 9 , number is also divisible by 9.

number = 2166564

sum of digits = 2+1+6+6+5+6+4 = 30

30 is not divisible by 9.

so, 2166564 is not divisible by 9

Divisibility rule of 4:

if last two digits are divisible by 4 , then number is also divisible by four.

number = 2166564

last two digits = 64

64 is divisible by 4.

so, 2166564 is divisible by 4.
