If σ(N) is the sum of all the divisors of N and τ(N) is the number of divisors of N then what is the sum of sum of all the divisors of first N natural numbers and the sum of the number of divisors of first N natural numbers?
Is there any relation between σ(N) and τ(N) functions?
Can I do that without factorizing any of the number in the sequence?
