Which pair are prime factors of 12?

Explanation:
Prime factors are the prime numbers that multiply together to form the original number. For 12, you can factor it by dividing by the smallest prime, 2: 12 = 2 × 6, and then 6 = 2 × 3. So the prime factors are 2, 2, and 3; the distinct prime factors are 2 and 3. Both 2 and 3 are prime and divide 12, which is why they form the correct pair. The other options include numbers that aren’t prime (like 4 and 6) or a prime that doesn’t divide 12 (like 5), so they aren’t correct prime factors of 12.
