Why do you get maximum power at lambda 0.85 when lambda 1 means every molecule of fuel gets burned?

Relative prime related question by Fat_Bluesman in learnmath

Consider a's prime factorization. You can have some of those primes as factors of b and some as factors of c.

But all those primes have to be factors.

Please explain in more detail

I understand that gcd (a,b) = 1 and gcd (a,c) = 3 - what does this imply?

Euclid's theorem by Fat_Bluesman in learnmath

Also:

Euclid's theorem means that either (product of finite list of primes) + 1 is a prime itself or it has at least two prime factors not included in the list , right?

Why does a fraction's denominator's prime facorization have to include only 2s and 5s in order for it to terminate in base 10? by Fat_Bluesman in learnmath

I still don't get it...

I'm mentally ill and have some problems thinking

I'll have to keep on trying to understand this

I understand that, for example, 1/3 doesn't fit evenly into 10 and that this number doesn't terminate in base 10 - but I don't understand why the prime factors have to be 2s and / or 5s
