62 (sixty-two) is a natural number following 61 and preceding 63. It is a composite number with the divisors 2 and 31 being the eighteenth discreet semiprime. 62 has an aliquot sum of 34; itself a discrete semiprime, and the 10 member aliquot sequence (62,34,20,22,14,10,8,7,1,0). 62 is therefore the tenth member of the 7-aliquot tree. It is a nontotient, and a repdigit in base 5 (222). 62 is also the only number whose cube (238328) consists of 3 digits each occurring 2 times.^[1] Sixty-two is the atomic number of samarium, a lanthanide, and the code for international direct dial calls to Indonesia. Sigmund Freud had an irrational fear of the number 62^[2]

In the 1998 Home Run Race, Mark McGwire hit his 62nd home run on September 8, breaking the single-season record. Sammy Sosa hit his 62nd home run just days later on September 13.
