3×41

3×41 is the product of the integers 3 and 41. In decimal arithmetic it equals 123.

Calculation and properties: 3×41 can be computed as 3×(40+1) = 120+3 = 123. The prime factorization is 3×41, since both 3 and 41 are prime numbers. Therefore, 123 is a semiprime—a product of exactly two primes. Its positive divisors are 1, 3, 41, and 123.

Representations and notation: In decimal, the product is 123. In binary, 123 is 1111011; in hexadecimal, it is 0x7B. In Roman numerals, 123 is CXXIII. The decimal code 123 corresponds to the ASCII character “{”.

Context and relevance: 3×41 serves as a straightforward example in elementary arithmetic and number theory, illustrating the distributive property and the concept of semiprimes. Both factors, 3 and 41, are primes, highlighting how a composite number can arise from the product of two primes. The number 41 is itself notable in various mathematical contexts and is part of the twin-prime pair (41, 43).
