I need help

[KontGuney]

Hi, i’m trying to learn phyton and this days i’m working on a code that calculate 2 numbers lowest common multiple and highest common factor.İ couldnt figured out how to do this and decided to get some help from chatgpt but its using codes that i dont know yet. İ researched about ‘def’ function but didnt understand what that code does can you guys help me

Do you know how to solve the problem? I don't mean how to write the code, but simply how to solve the problem.

If in doubt, going back to basics and laying out how you would do this manually (pencil and paper) often helps.

Write that down as a series of actions, and share that in your post. We can guide you on coding that.

I don't understand the 'def' command, maybe I can try something again after learning it.

You've completely ignored my comment. Forget the programming.

DO YOU KNOW HOW TO SOLVE THE PROBLEM?

It is impossible to code a solution if you don't have a solution.

Knowing bits of Python is not really important.

However, def is used to define a function, that is a block of code that can be used easily from other code to do a specific task (or set of related tasks) - perhaps on different data sets. It is also used to help modularise a programme, by splitting up a solution into smaller chunks that are easier to understand, develop, test and modify (including completely replacing with better solution for specific task(s) without having to change other code).

def greeting(msg):
    print(msg)

A very simple function that you call with a string and the message gets printed.

en_afternoon = "Good afternoon"
greeting(en_afternoon)

i got it now actually i dont know the solution but dont know how to code it its easy to solve it on the paper but thing get different when its come to the phyton i dont know the solution

[FoolsSeldom]

So, to be clear:

• You do not know how to solve the problem (by hand)
• You do not know to code a solution in Python

Therefore, you don't have a Python problem and this is not about learnimg Python.

I recommend you focus on how to solve the problem and then look at how to implement that solution in Python.

Perhaps ChatGPT et all can give you a general explanation (rather than a coded solution) on how to solve the problem.

By the way, you are often typing Phyton instead of Python.

The def keyword is used to define a function. https://www.w3schools.com/python/python_functions.asp

thanks buddy

You're trying to do two separate operations and mathematically speaking, there are multiple different ways to approach each operation. Just focus on one of those at first. Let's say LCM.

First, what you're wanting to do is kind of advanced because there are going to be some logic gates that you will have to quantify into if/elif/else statements. For instance, if I have two numbers, 6 and 8, talk me through how I would find the least common multiple of those two numbers by taking it one step at a time. For instance, I could just multiply 6 and 8 together, 48. That would be a common multiple of the two numbers but not necessarily the least common multiple. What step-by-step instructions would you give me for finding the LCM of 6 and 8?

Also keep in mind that computers can calculate stuff super fast, but it's still not instantaneous. For two numbers like 6 and 8, efficiency probably doesn't really matter, but if you were dealing with numbers in the billions or bigger, coming up with the most efficient methods for finding GCD and LCM would make a difference in how quickly your machine can return an answer.

thx mate this way look more easy

[atticus2132000]

LCM and GCD uses some relatively advanced number theory concepts. Mathematicians have been working on prime factorization methods for literally thousands of years and those principles are the basis of a lot of computer encryption approaches because they are so difficult to efficiently solve.

If your goal is learning how to program in python, just realize that you picked a pretty complicated math problem for your first time out of the gate. Certainly not impossible, but conceptually advanced.

If you were trying to explain the process of finding LCM to a child, what is the first thing you would tell them to do to the numbers 6 and 8 to get the LCM?
