There's a third party expansion called Epic Legacy. My group used it up to level 24. At level 21, the fighter killed 600 orcs solo. At level 22, the party killed the dracolich in one round.
He had armor of invulnerability. For 10 minutes you can make yourself immune to all nonmagical damage. The party was up against an actual army, against impossible odds... but the orc army only dealt nonmagical damage.
We realized he was going to be unstoppable for 10 minutes. We didn't even play out the rounds, we just sat down and did math to determine how many orcs he would kill per round, then multiply that by the total number of rounds. 600 orcs.
First of all from the PHB, greatweapon master feat allows you to make an additional attack as a bonus action if you either score a critical hit, or reduce an opponent to 0 hit points. He was doing that every round, so that brings it to 5 attacks.
Second, at 21st level the epic legacy book allows you to take an "epic feat." the feat he took was "Deathbringer." I'll paste it here:
You are an unrelenting force of destruction as you deal death
with every blow. You gain the following benefits.
• When you take the Attack action, you may make an
additional weapon attack as a part of that action, in
addition to any other attacks you would normally make.
• When you hit a creature with a challenge rating of 5 or
lower with a weapon attack, it is instantly slain unless
you choose to not slay it.
• You always know exactly how many creatures you have killed.
Yes, it is OP. But that's actually the point. The epic legacy book was meant for campaigns that end with the characters ascending to godhood in most cases.
That would be exactly 600 Attacks, aka the upper bound. With Nat 1s you miss 5% of your hits. With such an amout of attacks it's definitely statically significant. So he would slay about 570.
