Ep 4. GRE Arithmetic: Integers (Part 4 of 4) | Even, Odd, Prime Factorization, Composite Numbers

In season 1 episode 4 of GRE Math Review, the focus is on the topic of integers, specifically even and odd numbers, prime factorization, and composite numbers. This is the final part of a 4-part series on the topic of arithmetic.

The episode begins with a review of even and odd numbers. The host explains that an even number is a number that can be divided evenly by 2, while an odd number cannot. They provide several examples and highlight the fact that 0 is considered an even number. They then move on to discuss the properties of even and odd numbers, such as the fact that when even and odd numbers are added or subtracted, the result is always odd.

They provide several examples and highlight the fact that prime factorization can be used to find the greatest common factor and least common multiple of two numbers.

After discussing prime factorization, the episode moves on to the topic of composite numbers. These are numbers that can be divided evenly by numbers other than 1 and themselves. The host provides several examples and highlights the fact that composite numbers can be broken down into their prime factors.

Throughout the episode, the host provides tips and tricks for solving problems involving even and odd numbers, prime factorization, and composite numbers. They also provide several practice problems for viewers to work through on their own, with step-by-step solutions provided at the end.

Overall, season 1 episode 4 of GRE Math Review is a comprehensive review of the fundamental concepts of arithmetic, with a focus on even and odd numbers, prime factorization, and composite numbers.
