An asymptotic formula is given for the number of integers n ≤ x for which φ( n ) is not divisible by a given odd prime. BK Spearman,KS Williams - 《Arkiv För Matematik》 被引量: 45发表: 2006年 Odd perfect numbers have a prime factor exceeding 10 7 bound for the largest prime ...
In case of 77 and 3535 the number of cases should be 66 as 0<ai<70<ai<7. When the sum is 1414, favourable outcomes are: (146)−6((75)+(65)+1).(146)−6((75)+(65)+1). I tried this by a variation of beggars method. Let's assume there ...
