Ruth-Aaron Pairs
A Ruth–Aaron pair consists of two consecutive integers (e.g. 714 and 715) for which the sums of the distinct prime factors of each integer are equal. These types of pairs were named by Carl Pomerance, uga math professor, after a student noted that 714 and 715 had this characteristic. 714 was the number of career homeruns hit by the Yankee legend Babe Ruth, while 715 was the number of career homeruns hit by Brave legend Hank Aaron in 1974, thus surpassing Ruth's all time home run record which had stood for almost 40 years.
