There are an infinite number of numbers that are a multiple of 3 & 5 and have [exactly] 8 factors. The lowest is 30.
The next few are: 105, 135, 165, 195, 255, 285, 375, 435, ...
Any number of the form 15p where p is a Prime number (which is 2 or greater than 5) will be a multiple of 3 & 5 and have exactly 8 factors.
p=2 gives 15 x 2 = 30, p=7 gives 15 x 7 = 105, etc.
There are two further numbers (listed above): 135 (= 15 x 9) & 375 (= 15 x 25).

Can you explain to me why the multiples of any number other than 1 are not prime numbers?
Sure! The multiples of a number other than 1 will always have at least three factors: 1, the number itself, and the multiple. This means they are not prime numbers, as prime numbers only have two factors: 1 and the number itself. For example, the multiples of 2 will always be divisible by 2, making them composite numbers rather than prime.

Is 356 a multiple of 6?
To be a multiple of 6 a number must be even and a multiple of 3.356 is not a multiple of three. The short cut to that is if the digits add up to a multiple of three then the original number is a multiple of 3.
