Integer Properties
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 sequence 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 practical application of these concepts is demonstrated through a problem-solving example, reinforcing the importance of understanding the relationship between multiples and factors.
