Published online by Cambridge University Press: 20 November 2018
Extract
Let 0<a1<…<an be integers and (a, b) denotes the greatest common divisor of a, b. R. L. Graham [1] has conjectured that
for some i and j. In a recent paper Weinstein [2] has improved Winterle's result [3] and has proven the following interesting theorem:
If A is the sequence a1< … <an where ak = P, a prime for some k and , then
