What are the Factors of 8?
1,2,4,8
Is 17 a Prime number?
Yes
Name 3 Composite numbers between 1-15
4,6,8,9,10,12,14,15
What is the GCF of 3 and 15?
3
What is the LCM of 8 and 12?
24
Give me a definition of Factors.
Factors are numbers that divide the given number without leaving a remainder. An example could be, the factors of 9 are, 1,3, and 9.
What's the difference between Prime and Composite numbers?
Prime numbers have 2 factors (1 and itself) while Composite has more than 2. Example, 5 only has 2 factors, 5 and 1. That means 5 is a Prime number. On the other hand, Composite has more than 2, so 4 would be Composite because 4 has more than 2 factors, 4's Factors are 1,2, and 4.
True or False
Is 27 a Composite number?
True
Give me a definition of Greatest Common Factor and give an example.
GCF stands for Greatest Common Factor. GCF is the largest number that divides evenly into 2 or more numbers. Example, the GCF of 3 and 12 is 3 because that is the largest number that divides evenly into 3 and 12.
Give me a definition of Least Common Multiple and give me an example.
LCM stands for Least/Lowest Common Multiple. LCM means the smallest multiple that 2 or more numbers have in common. An example could be 12 and 9. What are the first few multiples of 12? 12,24,36, and for 9, it would be 9,18,27,36. So the LCM would be 36 because is was the first common multiple between the numbers.
What are the Factors of 87?
1,3,29,87
True or False
Is 119 a Prime number?
False, 1,7,17,119
What are Composite Numbers?
Composite Numbers are basically the opposite of Prime numbers. Prime numbers have 2 factors while Composite have more than 2. An example is 8, it has 4 factors, 1,2,4, and 8.
Is there a difference between GCF and GCD?
There is no difference between GCF and GCD. GCD stands for Greatest Common Divisor.
True or False
The LCM of 18 and 42 is 74
False, the LCM is 126
What is a Factor Tree?
It has to be a clear definition. If it's not clear no points.
Gurkirat the Host will decide.
An example is 18
9 x 2
3 x 3 x 2
The Prime Factorization of 18 is 3x3x2
A factor tree is used in math to break down a composite number into its prime factors.
Make a good joke about Prime Numbers. Mr. Porco will decide if it was funny or not.
Nice Joke!
1 person in your group will turn around the opposite way of the Projector. I will show a Composite Number on the Projector and the people in your group will be the Helpers, Helpers will help you get the number. RULES For the HELPERS: 1. Only 2 WORDS, 2. Can't say the Number (Example: You can't say Twenty-six), 3. You can not do move along sentences like, Helper 1 says "The number," Helper 2 says "Is sixty," Helper 3 says "four." 4. You can't do cheesy hints, Example: You can't say hints too specific, I think everyone knows what specific hints are. 5. Every Helper gets 2 rounds of helping him get the number. 6. DO NOT CHEAT, IF YOU DO, NO POINTS!
