The first 3 primes are 2,3,5 and their product
is 30, which ends in 0.
But 30 times any number always ends in 0
since 30 is a multiple of 10.
So 30 times the product of the next 9997
primes also ends in 0.

Pattern?
List the products:
(2) 2; (3) 6; (5) 30; (7) 210; (11) 2310; (13) 30,030; (17) 510,510; (19) 9,699,690;
There will always a zero at the end after 5.

It will be zero. Both 2 and 5 are primes, so any such product must be a multiple of 10.
