The Tur OC 101 discusses how much of the sh'mone esre (amida) one needs to have concentration on while saying. Amid that, he writes:
The rabbi, Rabbi Eliezer, wrote that a person should accustom himself that he has concentration, at least, for the closure of each benediction. For they have, [all told,] one hundred thirteen words, just as there are [one hundred thirteen words] in the prayer of Chana and one hundred thirteen times "lev" [="heart"] in Chumash, to indicate that one needs to have concentration of the heart for them.
This answer previously had less info in it and cited a later source. Many thanks to Y ez for pointing me to the Tur.
Chanoch lived for 300 years after he begat Mesushelach. Mesushelach was 187 when he begat Lemech. So, when Chanoch was "no longer", Lemech was...113!
113 is the number of the final daf in Sanhedrin.
