我的问题是编写一个python程序来从文件中读取2个数字，并将这2个数字的gcd和lcm写入第二个file.This，这是我的代码

import math

def gcd(a, b):
    while b != 0:
        a, b = b, a % b
    return a

def lcm(a, b):
    return abs(a * b) // math.gcd(a, b)

def read_numbers_from_file(file_path):
    with open(file_path, 'r') as file:
        numbers = file.readline().split()
        return int(numbers[0]), int(numbers[1])

def write_gcd_lcm_to_file(file_path, gcd_value, lcm_value):
    with open(file_path, 'w') as file:
        file.write(f"GCD: {gcd_value}\n")
        file.write(f"LCM: {lcm_value}\n")

# 从第一个文件中读取两个数字
input_file_path = 'input.txt'
a, b = read_numbers_from_file(input_file_path)

# 计算最大公约数和最小公倍数
gcd_value = gcd(a, b)
lcm_value = lcm(a, b)

# 将结果写入第二个文件
output_file_path = 'output.txt'
write_gcd_lcm_to_file(output_file_path, gcd_value, lcm_value)
