What makes 62 notable
- Semiprime. 62 = 2 × 31, a product of exactly two primes. That gives it just four divisors, so it splits into equal groups in only two non-trivial ways.
62 in everyday use
Sixty-two is the atomic number of samarium, a rare-earth metal used in the strong magnets of headphones and small motors. One hundred kilometres is a little over 62 miles, a conversion runners and drivers crossing borders learn quickly. The rhombicosidodecahedron, one of the thirteen Archimedean solids, has 62 faces: twenty triangles, thirty squares, and twelve pentagons.
Sixty-two is 2 × 31, twice a Mersenne prime, and can be written as a sum of three distinct squares in two different ways: 1 + 25 + 36 and 4 + 9 + 49. It is a nontotient — no whole number has exactly 62 numbers below it that share no factor with it. In binary it is 111110, five ones followed by a zero, because it is one less than 63.
