​ ​求各位大神帮忙解决python编程作业题，谢谢大家

def gcd(a,b):
    if a < b:
        temp = b
        b = a
        a = temp
    remainder = a % b
    if remainder == 0:
        return b
    else:
        return gcd(remainder,b)

def lcm(a,b):
    remainder = gcd(a,b)
    result = a*b/remainder
    result2 = str(result)
    print(str(a) + '和' + str(b) + '的最小公倍数是：' + str(a*b/remainder) )

lcm(6,9)
