    Hello,

    A={x:x is a prime factor of 30}

    we will find all the prime factors of 30 and include them in set A

    ∴A={1,2,3,5,6,10,15,30}

    similarly for set B

    B={1,2,3,4,6,8,12,24}

    A∪B={1,2,3,4,5,6,8,10,12,15,24,30}

    union is all the components of 2 or more sets and writing the common components 1 time

    A∩B={1,2,3}

    intersection means the common elements of 2 or more sets

    hope this helps
