  1. 1. (a) twoA prime has exactly two factors: 1 and itself.
  2. 2. (d) 42 and 35Both 35 (7×5) and 42 (7×6) are multiples of 7.
  3. 3. (c) its digit sum is divisible by 3The digit-sum rule decides divisibility by 3.
  4. 4. (d) 11 is neither prime nor composite.
  5. 5. A number is divisible by 9 if the sum of its digits is divisible by 9.
  6. 6. A factor divides the number exactly; a multiple is obtained by multiplying the number by a whole number.
  7. 7. Write each as primes: 12 = 2×2×3 and 18 = 2×3×3. For the HCF, take the common prime factors with the lowest powers: one 2 and one 3, giving HCF = 6. For the LCM, take all prime factors with the highest powers: 2×2 from 12 and 3×3 from 18, giving LCM = 2×2×3×3 = 36. Check: HCF × LCM = 6 × 36 = 216 = 12 × 18.
