Look at the picture! Express the following set in set-builder notation ?
Alex

Answer:

A.   E={x|x\in N and x is a multiple of 8}

Step-by-step explanation:

Let x represent the set of natural numbers. Then we can write;

x\in N.

The set of all natural numbers that are multiples of 8 is then written as;

x\in N and x is a multiple of 8.

E is the set of natural numbers that are multiples of 8 can then be written in set builder notation as;

E={x|x\in N and x is a multiple of 8}

The correct choice is A

Peter's Party Zone sells cups in packages of 666 and plates in packages of 888.
Amiraneli [1.4K]
Prime factorize the two numbers:

666 = 2 x 3 x 3 x 37
888 = 2 x 2 x 2 x 3 x 37

Notice I lined up all the numbers into columns. If they appear for both numbers they are paired. The lowest common multiple is the product of all the unique columns:

LCM = 2 x 2 x 2 x 3 x 3 x 37 = 2664

You can use this strategy for as many numbers as you want. Also, you could find the greatest common factor by multiplying only the paired columns.
