Summary
The content provides an in-depth exploration of the concepts of multiples, factors, and divisors, emphasizing their interrelationships and applications in mathematical problem-solving, particularly in the context of preparing for the GMAT exam.
  • Multiples and factors have an inverse relationship; if P is a multiple of r, then r is a factor of P.
  • Every positive integer is a multiple of 1 and itself, highlighting the universal applicability of these concepts.
  • To find multiples of a number, one can multiply it by a series of integers or add the number to itself repeatedly.
  • If P and Q are multiples of r, operations such as addition, subtraction, or multiplication on P and Q will result in more multiples of r.
  • A practice problem illustrates how to apply these concepts to identify possible values of P given a set of conditions.
