输入两个整数，判断它们是否互质(标签-ar)

python
题目描述
输入两个整数，判断它们是否互质。
输入
输入两个整数a，b，每行一个。
输出
输出它们是否互质，如果互质的话，则输出：a and b are coprime，否则输出: a and b are not coprime。
样例输入
2
3
样例输出
2 and 3 are coprime

使用辗转相除法求

def gcd(a,b):
    n,m = a,b
    if a > b:
        a,b = b,a
    while a > 0:
        a,b = b%a,a
    if b != 1:
        print(f"{n} and {m} are not conprime") 
        return
    print(f"{n} and {m} are conprime")
n = int(input())
m = int(input())
gcd(n,m)

辗转相除，看最大公因数是否等于1

def gcd(m, n):
    return n if (m == 0) else gcd(n % m, m)


if __name__ == '__main__':
    m, n = map(int, input().split())

    print("%s\n", "{} and {} are coprime".format(m, n) if (gcd(m, n) == 1) else "{} and {} are not coprime".format(m, n))
