Learn Prime Numbers, Factors & Composite Numbers

Welcome to our YouTube channel dedicated to exploring the fascinating world of factors, prime, and composite numbers. Whether you're a student struggling with math homework, a teacher looking for new teaching materials, or simply a curious mind seeking to expand your knowledge, this channel has something for you.

In our videos, we break down the concepts of factors, prime, and composite numbers into easy-to-understand explanations and examples. We cover everything from the basic definitions and properties to more advanced topics like finding prime factors, prime number patterns, and prime factorization.

Our goal is to help you not only understand these concepts but also appreciate the beauty and importance of numbers in our daily lives. For example, did you know that prime numbers are essential to modern cryptography and online security? Or that the discovery of prime numbers dates back to ancient civilizations like the Greeks and the Egyptians?

In addition to our educational content, we also provide practice problems and solutions to help you test and improve your math skills. And if you're a visual learner, we offer interactive graphics and animations that bring these concepts to life.

So, whether you're a beginner or an advanced learner, join us on this journey of discovery and exploration. Don't forget to like, share, and subscribe to our channel for more videos on factors, prime, and composite numbers. Let's dive in and unlock the secrets of math together!

You are good just wished we did some much larger numbers on the number tree

... So, if I understood your presentation well, it means that the only even number which can be a prime number is number 2 ...

Thank you for your good jobs in sharing your knowledge with other people.

1 is neither a composite number nor a prime number. It's because, it doesn't figure in the prime factorisation tree.

Check if a is prime number program:
a - integer variable 'our number to check
b - integer variable 'loop counter
c (2 to a-1) - integer variable 'modulo (rest from dividing) of a and b
d - binary variable 'switch equal 0 if a is the prime number and 1 if a isn't prime number

d=0
set a value from input
if a=0 or a=1 then
d=1
else
end if

if a=2 then
d=0
else
end if

For b=2 to b=a-1
c(b) = a mod b
if c(b)=0 then
d=1
b=a-2 'stop this for loop
else
end if
next b

if d=0 then
echo: "a - is prime number"
else if d=1 then
echo: "a - isn't prime number"
end if
