Yes. In fact, it's the smallest prime number that's expressible as a product of two primes.

>>12513607
only in base 10

Nigga this shit is base independent.

In base 57, the number becomes 10, which is clearly divisibly by 5.

>>12513605
No
19 * 3 = 52
add 5 and you get 57
so its not prime

This joke makes no sense when you realize they are talking to each other. "Base 10" is not "base ten" unless 10 is ten.

57 = 19*3. both 19 and 3 are primes and since the space of all prime numbers is closed under multiplication, so is 57.

>>12513605
5+7=12=>1+2=3
so no, it's dividable by 3

>> No.12513892

>>12513884
please tell me this is bat
5+7-4 = 8, add the remaining 5 and it's 13
