## Multiples

Summary
The content delves into the concepts of multiples, factors, and divisors, elucidating their interrelationships and applications in mathematical problem-solving, particularly in the context of the GRE 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 fundamental nature of multiples in mathematics.
• To find multiples of a number, one can add or subtract that number repeatedly or multiply the number by a sequence of integers.
• 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 demonstrates how to apply these concepts to identify possible values of P given a set of conditions.
