I have found a round white pill that has the numbers 44 104. What is this?

Pill imprint 44 104 has been identified as Acetaminophen 325 mg.

Acetaminophen is used in the treatment of pain; muscle pain; sciatica; fever; neck pain (and more), and belongs to the drug class miscellaneous analgesics. Risk cannot be ruled out during pregnancy. Acetaminophen 325 mg is not a controlled substance under the Controlled Substance Act (CSA).
