7 divisibility rule - the last digit of the given number should be multiplied by 2 and then subtracted with the rest of the number leaving the last digit.
eg) 14 -> 4 x 2 = 8 -> 1 - 8 = -7 ÷ 7 = -1 (perfect no.)
hence we can say 14 is divisible by 7
similarly 65432 - 0 x 0 = 65432 ÷ 7 = is not a perfect no. bcoz ans is in decimals.
Hence, 654320 is not divisible by 7.
