Given :
the numbers less than 100 that are the product of exactly three different prime numbers
Lets write some prime numbers
[tex]2,3,5,7,11,13,17,19,23,29,31,37............[/tex]
Lets multiply three prime numbers and check which one gives us a number less than 100
[tex]2 \cdot 3 \cdot 5=30\\2 \cdot 3 \cdot 7= 42\\2 \cdot 3 \cdot 11 = 66\\2 \cdot 5 \cdot 7 = 70\\2 \cdot 3 \cdot 13= 78\\[/tex]
