The product of all the prime numbers less than 15 is closest to which of the following powers of 10?  Pick one
A) a) 10^4  B) b) 10^8  C) c) 10^7  D) d) 10^6  E) e) 10^5
Group these numbers so as to get product close to a multiple of 10, so they can be rewritten as (2*5)(3*7)(11*13) or 10*21*143   Now take out power of 10 from each number and rewrite   10*10*100*(1*2.1*1.43) or 10^4*(1*2.1*1.43)== 3.03*10^4   Which is greater than 10^4   a) 10^4.
