no because 6 is already a composite number. it's multiple can't be a prime number.
No, 426 is not a prime number. It is divisible by 2, 3, 6, 9, 142, and 213.
Yes that is correct
Yes, they are.
Any number that ends with 0, 2, 4, 6, or 8 is a multiple of 2.

No, 61 is not the multiple of 6. 60 and 66 is a multiple of 6. 61 is a prime number which is a number that can be divided by 1 and itself.

If the GCF of two numbers is 1, their LCM will be their product. Such numbers are called relatively prime, or co-prime. Any two prime numbers (like 3 and 5) will be that way, but the numbers don't have to be prime (like 4 and 9).

Any number that ends with 0, 2, 4, 6, or 8 is a multiple of 2.
Any number that ends with 0, 2, 4, 6, or 8 is a multiple of 2!
Any number that ends with 0, 2, 4, 6, or 8 is a multiple of 2.
It's an odd number so it obviously can't be divided by 2. The sum of its digits (1+6+5) is a multiple of 3, so the number itself is a multiple of 3. So it's not prime.
