Isn't statement no.2 just ridiculous ?
How on earth can 1 be regarded as a "PRIME NUMBER"
One is neither Prime nor Composite.
No, it is not at all ridiculous
Definition of Prime Number
A Prime number is a natural number with exactly two distinct natural number divisors: 1 and itself. Otherwise a number is called a composite number. Therefore, 1 is not a prime, since it only has one divisor, namely 1. A number n>1 is prime if it cannot be written as a product of two factors a and b, both of which are greater than 1: n = ab. |
Statement 2 is sufficient to state the x is a prime number...
Completely Disagree..!!!
How can someone say that 1 is a prime factor of a number.
One is neither prime nor composite.
In a way your statement is supporting my claim
statement 2 states => All the prime factors of x are 1 and itself.
How can one be a prime factor
The statement should be => All the factors of x are 1 and itself.
Big Difference
Yes, I agree. I missed that point. My Bad.
1 is a factor of a prime number BUT NOT a prime factor. 1 is neither prime nor composite.
Either the OA marked is incorrect or the question is incorrect.
