The 7 laws are embedded in the Torah.
To provide a brief summary, I have copied the following text from Wikipedia and the link is below.
The seven laws listed by the Tosefta and the Talmud are[7]
Prohibition of Idolatry
Prohibition of Murder
Prohibition of Theft
Prohibition of Sexual immorality
Prohibition of Blasphemy
Prohibition of eating flesh taken from an animal while it is still alive
Establishment of courts of law
The Noachide Laws comprise the six laws which were given to Adam in the Garden of Eden, according to the Talmud's interpretation of Gen 2:16,[8] and a seventh one, which was added after the Flood of Noah. Later, at the Revelation at Sinai, the Seven Laws of Noah were re-given to humanity and embedded in the 613 Laws given to the Children of Israel along with the Ten Commandments, which are part of, and not separate from, the 613 mitzvot. These laws are derived from the Torah. According to religious Judaism, the 613 mitzvot or "commandments" given in the written Torah, as well as their reasonings in the oral Torah, were only issued to the Jews and are therefore binding only upon them, having inherited the obligation from their ancestors. At the same time, at Mount Sinai, the Children of Israel were given the obligation to teach other nations the embedded Noachide Laws.[citation needed] These laws also affect Jewish law in a number of ways.
