Is the multiple of the prime number 7 also a prime number? Yes or no, explain WHY.
No. Any multiple of a prime number can be divided by the number it was multiplied by to create the multiple in addition to 1 and itself.
For example, 14 is a multiple of 7 but is not a prime number because its factors are 1,2,7,14, making it composite.
List the first five multiples of 15 AND all of the factors of 15.
Factors - 1,3,5,15
