117 of them.
32 of them.
They are: 16, 32 and 48 which makes three of them.
There are infinitely many of them so they cannot be listed. One of their multiples is 48*32 = 1536.
Since they are between, implying that 30 & 40 are not included, then the answer is 2: they are 32 & 36.
All the multiples of 64 are also multiples of 32.
There are an infinite number of multiples of 8; 8, 16, 24, 32, ...
The multiples of 4 between 23 and 49 are: 24, 28, 32, 36, 40, 44, 48.
