Prime Time

Aisha says every prime number is odd, so 2 cannot possibly be a prime number since it's even. Vikram disagrees. Who is right?

Meena says 24 is a factor of 12, because 12 times 2 equals 24. Kunal says that's backwards. Who is right?

Someone asks if 27 is a prime number. Tanvi says yes, because 27 is odd — it's not divisible by 2. Rohan says checking just one number, 2, is not enough. Who is right?

Kabir says 1 is a prime number, because its factors are just 1 and itself. His sister says 1 is neither prime nor composite. Who is right?

Priya says a bigger number always has more factors than a smaller number, because there's simply more room for things to divide into it. Arjun compares 36 and 37 and says that's not always true. Who is right?

Isha checks whether 49 is prime. She finds 49 is not divisible by 2, not by 3, not by 5 — and concludes 49 is prime. Her brother says she skipped a number she needed to check. Who is right?
