Sixty is the smallest number divisible by the numbers 1 to 6. (There is no smaller number divisible by the numbers 1 to 5). 60 is the smallest number with exactly 12 divisors.
Sixty is the sum of a pair of twin prime
s (29 + 31), as well as the sum of four consecutive prime
s (11 + 13 + 17 + 19). It is adjacent to two prime numbers (59,61). It is also the smallest number which is the sum of two odd primes in 6 ways.
The smallest non-solvable group
(A5) has order 60.
There are four Archimedean solid
s with 60 vertices: the truncated icosahedron
, the rhombicosidodecahedron
, the snub dodecahedron
, and the truncated dodecahedron
. The skeletons of these polyhedra form 60-node vertex-transitive graph
s. There are also two Archimedean solids with 60 edges: the snub cube
and the icosidodecahedron
. The skeleton of the icosidodecahedron forms a 60-edge symmetric graph
.
There are 60 one-sided hexomino
es, the polyomino
es made from 6 squares.
In geometry
, 60 is the number of seconds in a minute, and the number of minutes in a degree
. In normal space, the 3 interior angles of an equilateral triangle each measure 60 degree
s, adding up to 180 degrees.
Because 60 is divisible by the sum of its digits in base 10, it is a Harshad number
.
A number system with base 60 is called sexagesimal (the original meaning of sexagesimal is sixtieth).
The first fullerene
to be discovered was buckminsterfullerene
C60 - an allotrope of carbon
with 60 atom
s in each molecule
, arranged in a truncated icosahedron
. This ball is known as a buckyball, and looks like a soccer ball.
The atomic number

of sixty, inherited from the Sumerian and Akkadian civilizations, and possibly motivated by the large number of divisors which 60 has. The sexagesimal measurement of time and of geometric angles is a legacy of the Babylonian system.
The number system in the Mali Empire
was also based on sixty (this is reflected in the counting system of the Maasina Fulfulde
, a variant of the Fula language
spoken in contemporary Mali
). The Ekagi of Western New Guinea
have also used base 60, and the sexagenary cycle
also plays a role in Chinese calendar
and numerology.
In and in refer to 60 = 5 dozen
= 1/2 small gross
. This quantity was used in international medieval treaties e.g. for ransom of captured Teutonic Knights
.
, the number 60 occurs several times, for example as the age of Isaac
when Jacob
and Esau
were born, and the number of warriors escorting King Solomon
.
In the laws of kashrut
of Judaism
, 60 is also the proportion (60:1) of kosher to non-kosher ingredients which can render an admixture kosher post-facto.
In Islam, 60 was mentioned only once in the holy Koran: "..he should feed sixty indigent ones.."
