15 is the product of two prime numbers; 3 x 5

No. 15 is the product of two prime numbers: 3 and 5

All the numbers less than 100 that are the product of exactly three different prime numbers are 30, 42, 66, 70, and 78.

How about: 2*3*5 = 30 which is the product of the 1st three prime numbers

no

No.

56 = 7 x 8 = 7 x 23 then 56 is not a product of 3different prime numbers

No.

30, 42 and 70

All the numbers less than 100 that are the product of exactly three different prime numbers are 30, 42, 66, 70, and 78. Need to know how to get the answer

There are only two: 3 x 5

The LCM of any three distinct prime numbers is their product.

30, 42, 66, 70, 78

They are 30, 42, 63, 66, 70 and 78.

Since there are infinitely many primes, there are infinitely many numbers that are products of 3 primes.

Just 30

2 x 3 x 5 = 30

30, 42, 66, 78
