Abstract: We report the discovery of four transiting giant planets around K dwarfs. Theplanets HATS-47b, HATS-48Ab, HATS-49b, and HATS-72b have masses of$0.369_{-0.021}^{+0.031}$ $M_{J}$, $0.243_{-0.030}^{+0.022}$ $M_{J}$,$0.353_{-0.027}^{+0.038}$ $M_{J}$ and $0.1254pm0.0039$ $M_{J}$, respectively,and radii of $1.117pm0.014$ $R_{J}$, $0.800pm0.015$ $R_{J}$, $0.765pm0.013$$R_{J}$, and $0.7224pm0.0032$ $R_{J}$, respectively. The planets orbit closeto their host stars with orbital periods of $3.9228$ d, $3.1317$ d, $4.1480$ dand $7.3279$ d, respectively. The hosts are main sequence K dwarfs with massesof $0.674_{-0.012}^{+0.016}$ $M_{odot}$, $0.7279pm0.0066$ $M_{odot}$,$0.7133pm0.0075$ $M_{odot}$, and $0.7311pm0.0028$ $M_{odot}$ and with$V$-band magnitudes of $V = 14.829pm0.010$, $14.35pm0.11$, $14.998pm0.040$and $12.469pm0.010$. The Super-Neptune HATS-72b (a.k.a. WASP-191b and TOI294.01) was independently identified as a transiting planet candidate by theHATSouth, WASP and TESS surveys, and we present a combined analysis of all ofthe data gathered by each of these projects (and their follow-up programs). Anexceptionally precise mass is measured for HATS-72b thanks to high-precisionradial velocity (RV) measurements obtained with VLT/ESPRESSO, FEROS, HARPS andMagellan/PFS. We also incorporate TESS observations of the warm Saturn-hostingsystems HATS-47 (a.k.a. TOI 1073.01), HATS-48A and HATS-49. HATS-47 wasindependently identified as a candidate by the TESS team, while the other twosystems were not previously identified from the TESS data. The RV orbitalvariations are measured for these systems using Magellan/PFS. HATS-48A has aresolved $5.!!^{primeprime}4$ neighbor in Gaia~DR2, which is acommon-proper-motion binary star companion to HATS-48A with a mass of $0.22$$M_{odot}$ and a current projected physical separation of $sim$1,400 au.
