Million Dollar Question

For   both Teams 1 and Team 2
1,000,000 Question
What   is my number?

Clue 1 - My number is a multiple of 2 and 7.
Clue 2 - My number is less than 100, but
more than 50.
Clue 3 - My number is the product of 3
different prime numbers.
Since  the number is a multiple of 2 and 7,
it must be a multiple of 14. The multiples
of 14 between 50 and 100 are
56 = 2 x 2 x 2 x 7
70 = 2 x 5 x 7
84 = 2 x 2 x 3 x 7
98 = 2 x 7 x 7
So 70 is the only number that is a product
of 3 different prime numbers.
