Integer Properties Strategies

The content provides a comprehensive guide on strategies for tackling integer questions on the GRE, emphasizing the importance of understanding integer properties, recognizing the types of numbers involved, and applying specific strategies for different question types.
  • Ensure you're dealing with integers by looking for explicit statements in the question.
  • Don't forget about the possibility of zeros and negative numbers, and remember that prime numbers must be positive except for 2, which is the only even prime number.
  • Memorize prime numbers below 60, perfect squares of the first 15 integers, and understand the significance of prime factorization in solving problems.
  • For Greatest Common Factor or Least Common Multiple questions, remember to cancel before multiplying to simplify calculations.
  • Develop number sense and mathematical intuition through practice, rather than relying solely on memorized procedures.
