How many times is one to wash hands after cutting the nails?
Although from the letter of the law washing one time suffices[1], as stated above, some are accustomed to wash one’s hands three times [inconsecutively[2]].[3]

Other Opinions: Some Poskim rule that one is required to pour three times on his hand just like is required upon awakening in the morning. [Olas Tamid; Shlah Shaar Haosiyos 9; Lev Chaim 1:63; Kaf Hachaim [Falagi] 7:26; Ruach Chaim 4:3; Chesed Lealafim brought in Kaf Hachaim 4:61; Ben Ish Chaiy Toldos 17-wash inconsecutively; Kaf Hachaim 4:61 concludes that one who is stringent to wash three times after all the above actions is holy]
