134

134 is a natural number that follows 133 and precedes 135. It is even and composite, expressible as 2 × 67, with 67 prime. Thus it is a semiprime.

Its divisors are 1, 2, 67, and 134. The sum of proper divisors is 70, so 134 is a deficient number. It is not a perfect number.

In base representations, 134 equals 10000110 in binary, 206 in octal, 0x86 in hexadecimal, and CXXXIV in Roman numerals. The digital root is 8, since the sum of its digits (1 + 3 + 4) is 8.

In mathematics, 134 is an even composite and a semiprime, being the product of two primes (2 and 67). It is not a Fibonacci number, a square, or a cube. As an example among even integers in the 100s, it illustrates standard properties of semiprimes and factorization.
