As far as I can gather Psalms 145-150 and Psalms 114-118 were customary parts of the types of synagogue/local worship that Jesus would have been accustomed to on a regular, perhaps daily basis. Certain Psalms themselves contain repetitious elements (Psalm 118: "His steadfast love endures forever"). The Shema itself contains within it the command to recite it at least twice a day. Granted, Jesus probably didn't engage in something directly akin to the Rosary, repeating the same words 50 times in the span of 20 minutes but make no mistake He and the entire contingent of disciples would have been accustomed to praying certain prayers every day.
