It is not possible for any multiple of a Prime number to be prime.
Yes, the least common multiple (LCM) of a prime number and a composite number will always be a multiple of the prime number. This is because the LCM is the smallest number that is a multiple of both numbers. Since the prime number is a factor of itself and the LCM is a multiple of both numbers, the LCM will always be a multiple of the prime number.
Prime numbers only have two factors. A multiple of any number greater than one would have more than two.
There are a lot of possibilities. The seventh square number is 49. 5 times 5 times any other prime number will be greater than 49. 5 times any pair of prime numbers seven or greater will also satisfy the conditions.
No multiple of 86 is in that range. 43 is a prime number that is a factor of 86.
No even number greater than 2 is a prime, and 3640 is an even number.
Because if they were even they would be a multiple of 2 and thus not prime.
Usually it's 1, unless the composite number is a multiple of the prime number. Then, it's the prime number.
There is an infinite number of prime numbers. It is not possible to list them.
There is not a multiple of 7 that is prime.
15 is one possible answer.
Multiples of 2 are all even numbers, but no even number greater than 2 is a prime number. 2 divided by 1 is 2, a prime number.
Not all (5 is prime) but every multiple of 5 greater than 5 is composite because they have more than two factors. Every multiple of any integer greater than one is composite.
No. A notable exception is the set of prime numbers.
No, you can easily see that this is an even number, so it is a multiple of 2.2 IS A PRIME NUMBER!!Any number that is a multiple of a prime number is NOT a prime.

Prime numbers have only two factors. Multiples of any number greater than one have more than two.
No, it is not possible. Every multiple of 21 is a composite number. 21 is a composite number and its factors are 1, 3, 7 and 21(4 factors). Any multiple of 21 must have all the factors of 21. So, every multiple of 21 has at least 4 factors. And a prime number has only two factors so, any multiple of 21 can't be prime.
