Tutto quello che devi sapere sulla fattorizzazione in numeri primi
Cos'è la fattorizzazione in primi?
La fattorizzazione in numeri primi (o scomposizione) è la rappresentazione di un numero come prodotto di numeri primi. Per il teorema fondamentale dell'aritmetica, ogni intero > 1 ha una fattorizzazione unica in numeri primi.
A cosa serve la fattorizzazione?
La fattorizzazione è fondamentale in matematica e informatica: serve per calcolare MCM e MCD, semplificare frazioni, ed è alla base della crittografia RSA.
Come si trova il MCD e il MCM con la fattorizzazione?
Il MCD si trova moltiplicando i fattori comuni con l'esponente minore. Il MCM si trova moltiplicando tutti i fattori con l'esponente massimo. Es: 12=2²×3, 18=2×3² → MCD=2×3=6, MCM=2²×3²=36.
What is prime factorization?
Prime factorization is the representation of a number as a product of prime numbers. By the fundamental theorem of arithmetic, every integer > 1 has a unique prime factorization.
What is factorization used for?
Factorization is fundamental in mathematics and computer science: it is used to calculate LCM and GCD, simplify fractions, and is the basis of RSA cryptography.
How do you find GCD and LCM using factorization?
GCD is found by multiplying common factors with the smaller exponent. LCM is found by multiplying all factors with the larger exponent. E.g.: 12=2²×3, 18=2×3² → GCD=2×3=6, LCM=2²×3²=36.
Does my data stay private?
Yes, and not because we promise it: this tool runs entirely inside your browser. What you type or upload never leaves your device, so it never reaches a server of ours and there is nothing we could keep, read or lose. You can check it yourself: open the page, disconnect from the internet, and the tool keeps working.
Do you store what I enter?
No. There is no database behind this tool: we do not store your files, your text or your results. When you close the tab nothing is left — not here with us, because it never arrived, and not anywhere else.
Do you profile me? Are you GDPR compliant?
We do not profile you: there is no account to create, we never ask for your email to use a tool, and we keep no profile of what you do. We are an Italian company and we work under the GDPR and the other European rules, with the privacy notice and the consent request in plain sight. One thing we say in full rather than hiding it behind a slogan: the ads on the page are Google's, and Google may use cookies to personalise them. You decide from the consent banner: if you say no the ads stay, but they are not personalised, and the tool works exactly the same.
If it is free, how do you make money?
From the ads on the page, and that is all. We do not sell your data, there is no hidden paid plan, there is no limit that eventually asks for your card, and you do not have to sign up. The ads pay for the servers and for the time we spend writing the tools: that is how we can keep them open to everyone.
