17×53

17×53 is the product of the integers 17 and 53, which equals 901. The expression is a straightforward example of basic arithmetic multiplication.

Both factors are prime numbers, so 17×53 is a semiprime. It has exactly four positive divisors: 1, 17, 53, and 901. The prime factorization is simply 17×53, and no other primes divide 901. The product is commutative, so 17×53 = 53×17 = 901.

Numerical properties of 901 include that it is odd and not divisible by 3 or 5. The sum of its proper divisors is 1 + 17 + 53 = 71, which is less than 901, so 901 is a deficient number. The divisors occur in pairs around the square root of the number, which is approximately 30.

In other representations, 901 can be written as CMI in Roman numerals and as 1110000101 in binary. The pair of prime factors 17 and 53 are the 7th and 16th primes, illustrating the concept that a product of two distinct primes yields a semiprime. The example serves as a simple clear case in teaching multiplication and prime-factorization.
