They are 2,3 and 5
The product of the first three prime numbers (2, 3, and 5) is 30.
2*3*19
Their product is: 3*5*7*9*11*13*15*17*19 = 654,729,075
How about: 2*3*5 = 30 which is the product of the 1st three prime numbers
Find 3 consecutive numbers where the product of the smaller two numbers is 19 less than the square of the largest number.
16 and 3
5 * 2 * 3
How about: 2*3*5 = 30 as a product of its prime factors
30 is the product of three different prime numbers.
Two, three, and five have a product of thirty (2*3*5).
30 cannot be written as the product of 6 prime numbers. 30 has three prime factors: 2 x 3 x 5 = 30
19 doesn't belong. The rest of the numbers are multiples of 3.
