في الرياضيات

60 is a highly composite number.^[1] Because it is the sum of its unitary divisors (excluding itself), it is a unitary perfect number,^[2] and it is an abundant number with an abundance of 48. Being ten times a perfect number, it is a semiperfect number.
60 is a Twin-prime sum of the fifth pair of twin-primes, 29 + 31.
It is the smallest number divisible by the numbers from 1 to 6: there is no smaller number divisible by the numbers from 1 to 5 since any number divisible by 2 and 3 must be divisible by 6.
It is the smallest number with exactly 12 divisors. Having 12 as one of those divisors, 60 is also a refactorable number.
It is one of seven integers that have more divisors than any number less than twice itself (المتتالية A072938 في OEIS), one of six that are also lowest common multiple of a consecutive set of integers from 1, and one of six that are divisors of every highly composite number higher than itself. (المتتالية A106037 في OEIS)
It is the smallest number that is the sum of two odd primes in six ways.^[3]
The smallest nonsolvable group (A₅) has order 60.

The icosidodecahedron has 60 edges, all equivalent.

There are four Archimedean solids 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 graphs. 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 hexominoes, the polyominoes made from six squares.
In geometry, it is the number of seconds in a minute, and the number of minutes in a degree.
In normal space, the three interior angles of an equilateral triangle each measure 60 degrees, adding up to 180 degrees.
Because it is divisible by the sum of its digits in decimal, it is a Harshad number.
A number system with base 60 is called sexagesimal (the original meaning of sexagesimal is sixtieth).
It is the smallest positive integer that is written with only the smallest and the largest digit of base 2 (binary), base 3 (ternary), and base 4 (quaternary).
60 is also the product of the side lengths of the smallest whole number right triangle: 3, 4, 5, a type of Pythagorean triple.^[4]

The Babylonian cuneiform numerals had a base of 60, inherited from the Sumerian and Akkadian civilizations, and possibly motivated by the large number of divisors that 60 has.^{[بحاجة لمصدر]} The sexagesimal measurement of time and of geometric angles is a legacy of the Babylonian system.

The number system in the Mali Empire was based on 60, reflected in the counting system of the Maasina Fulfulde, a variant of the Fula language spoken in contemporary Mali.^[5] The Ekagi of Western New Guinea used base 60,^[6] and the sexagenary cycle plays a role in Chinese calendar and numerology.

From Polish–Lithuanian Commonwealth in Slavic and Baltic languages 60 has its own name kopa (پولندية: kopa, بالبيلاروسية: капа́, لتوانية: kapa, تشيكية: kopa, روسية: копа, أوكرانية: копа́), in Germanic languages: ألمانية: Schock, دنماركية: skok, هولندية: schok, سويدية: Skock, نرويجية: Skokk and in لاتينية: sexagena 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.
