## Multiples

Summary

The content delves into the concept of multiples, factors, and divisors, elucidating their interrelationships and implications for 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 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 demonstrates how to apply these concepts to deduce possible values of P given a set of conditions.
