A receiver includes a multiphase mixer that multiplies a received radio signal by multiphase local signals the number of which is the same as an integer having a first prime factor and a second prime factor different from the first prime factor, and generates first multiphase baseband signals the number of which is the same as the integer, a first processing circuit that suppresses common modes for first multiphase signal groups formed by dividing the first multiphase baseband signals into groups of signals the number of which is the same as the first prime factor, and generates second multiphase baseband signals, and a second processing circuit that suppresses common modes for second multiphase signal groups formed by dividing the second multiphase baseband signals into groups of signals the number of which is the same as the second prime factor, and generates third multiphase baseband signals.
