Find the minimum number in [ low . . high ] that is a multiple of prime . get ( i ) ( divisible by prime . get ( i ) ) For example , if low is 31 and prime . get ( i ) is 3 , we start with 33.
int loLim = ( int ) ( floor ( low / prime . get ( i ) ) * prime . get ( i ) ) ; if ( loLim < low ) loLim += prime . get ( i ) ;
