35

35 = 5 x 7.

35 is the sum of the cubes of the first two primes: 23 + 33 = 35.

The product of
35 and 36 has the same prime factors as the product of 4374 and 4375.

35 can be written as a sum of odd primes in 35 ways, and as a sum of primes in 35 x 5 ways.

35 has a unique representation as a sum of three squares: 35 = 12 + 32 + 52.

35 is the smallest number with five representations as a sum of three distinct primes: 35 = 3 + 13 + 19 = 5 + 7 + 23 = 5 + 11 + 19 = 5 + 13 + 17 = 7 + 11 + 17.

35 is the fifth tetrahedral number (the sum of the first five triangular numbers).

35 is the fourth pentatope number.
