The product of all the prime numbers less than 28 is closest to which of the following powers of 10?	Choices:  A) a) 10^9  B) b) 10^8  C) c) 10^7  D) d) 10^6  E) e) 10^8*2.23
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*19)(13*17)*23 or 10*21*209*221*23   Now take out power of 10 from each number and rewrite   10*10*100*100*10(1*2.1*2.09*2.21*2.3) or 10^7*(1*2.1*2.09*2.21*2.3)=2.23*10^8   e) 10^8*2.23
