60 is two times the product of the three smallest primes (2*3*5 = 30).

Whoooaaa... Heavy, man.

Dig it in binary:

1*(2^5) + 1*(2^4) + 1*(2^3) + 1*(2^2) + 0*(2^1) + 0*(2^0) = 32 + 16 + 8 + 4 = (111100) base2

What's a left bit shift? Oh yeah, multiplication by 2:

1111000 = (120) base10

Like wow, man: (2*2*2)*(3*3)*5 = (2^3)*(3^2)*(5^1) = 8*9*5 = 8*45 = 360.

It must mean something.
