Here, we will read two integer numbers from the user. Then we will find the Lowest Common Multiple and print the result.

Program/Source Code:

The source code to find the LCM (Lowest Common Multiple) is given below. The given program is compiled and executed successfully.

// Rust program to find the LCM 
// (Lowest Common Multiple)

use std::io;

fn main() 
{
    let mut n1:i32 = 0;
    let mut n2:i32 = 0;
    let mut rem:i32= 0;
    let mut lcm:i32= 0;
    let mut x:i32  = 0;
    let mut y:i32  = 0;
    
    let mut input1 = String::new();
    let mut input2 = String::new();
    
    println!("Enter Number1: ");
    io::stdin().read_line(&mut input1).expect("Not a valid string");
    n1 = input1.trim().parse().expect("Not a valid number");

    println!("Enter Number2: ");
    io::stdin().read_line(&mut input2).expect("Not a valid string");
    n2 = input2.trim().parse().expect("Not a valid number");
    
    if (n1 > n2) {
        x = n1;
        y = n2;
    }
    else {
        x = n2;
        y = n1;
    }

    rem = x % y;

    while (rem != 0) {
        x = y;
        y = rem;
        rem = x % y;
    }

    lcm = n1 * n2 / y;
    println!("Lowest Common Multiple is: {}", lcm);
}

Output:

RUN 1:
Enter Number1: 
30
Enter Number2: 
5
Lowest Common Multiple is: 30

RUN 2:
Enter Number1: 
10
Enter Number2: 
125
Lowest Common Multiple is: 250

Explanation:

Here, we read the value of n1, n2 from the user. Then we found the LCM (Lowest Common Multiple) of n1 and n2. After that, we printed the result.
