The sum of two famous baseball records: the number of home runs hit by Babe Ruth (714), and the number of the home runs hit by Hank Aaron to break the Babe's record (715). The pair of numbers 714 and 715 is called a Ruth-Aaron pair because the sums of the prime factors of these consecutive integers are equal. The number 714 * 715 is also the product of the first seven primes (i.e., 7-primorial). [Trotter]
