Today is the 357 day of the year.
357 = 3 x 7 x 17
The fact that the prime factorisation consists of three distinct primes, none of which are raised to a power higher than one, means that 357 is a sphenic number by definition. As is shown here, all sphenic numbers have exactly 8 divisors. For 357 these divisors are: 1, 3, 7, 17, 21, 51, 119 and 357.
