2135274, or 2,135,274, is a natural number that follows 2,135,273 and precedes 2,135,275. In standard decimal notation it is even and thus divisible by 2. It is a composite number.

Its prime factorization is 2 × 3 × 23 × 15473. All prime factors are distinct, so the number is squarefree. Consequently, it has 16 positive divisors, obtained by multiplying any subset of its prime factors (including 1 and the number itself). The factor 15473 is itself a prime number, verifiable by checking divisibility by primes up to its square root.

Arithmetic functions for this number include Euler’s totient φ(2135274) = 680,768 and the sum of divisors σ(2135274) = 4,456,512. Because its digit sum is 24, the number is divisible by 3; combined with its divisibility by 2, it is divisible by 6 as well. The combination of small and large prime factors makes 2135274 a useful example of a squarefree, four-prime product in number-theory discussions.
