Weekly Assignments

Discussion Board - 35 pts. 3 posts with mathematical content (1 answering

the posted question, two interacting with me and fellow students

Must have mathematical content to count toward posts (For Example: “I like that!” Or “I agree” are nice and appreciated, but will not count toward your credit).

Posts do not have to be “perfect” to get credit

1.1

Number Theory

Slide 5 - 10Copyright © 2009 Pearson Education, Inc.

Prime and Composite Numbers

A prime number is a natural number greater than 1 that has exactly two factors (or divisors), itself and 1.

A composite number is a natural number that is divisible by a number other than itself and 1.

The number 1 is neither prime nor composite, it is called a unit.

Example of branching method

Therefore, the prime factorization of

3190 = 2 • 5 • 11 • 29.

Greatest Common Divisor

The greatest common divisor (GCD) of a set of natural numbers is the largest natural number that divides (without remainder) every number in that set.

Slide 5 - 13Copyright © 2009 Pearson Education, Inc.

Example (GCD)

Find the GCD of 63 and 105.

63 = 32 • 7

105 = 3 • 5 • 7 Smallest exponent of each factor:

3 and 7 So, the GCD is 3 • 7 = 21.

Least Common Multiple

The least common multiple (LCM) of a set of natural numbers is the smallest natural number that is divisible (without remainder) by each element of the set.

Slide 5 - 15Copyright © 2009 Pearson Education, Inc.

Example (LCM)

Find the LCM of 63 and 105.

63 = 32 • 7

105 = 3 • 5 • 7 Greatest exponent of each factor:

32, 5 and 7 So, the LCM is 32 • 5 • 7 = 315.
