Question

so the prime factor of 5​

Answer 1

Answer:

, 5 is a prime number since the only factors of 5 are 1 and 5.

Answer 2

Answer:

A key point to note is that the two factors must be different, so 1 is not a prime number since both factors of 1 are the same. For example, 5 is a prime number since the only factors of 5 are 1 and 5. 6 is not a prime as, apart from 1 and 6, other factors exist - 2 and 3.
