Python| math.gcd()函数

在Python中，数学模块包含许多数学运算，可以使用该模块轻松执行。 math.gcd()函数计算其参数中提到的 2 个数字的最大公约数。

Syntax: math.gcd(x, y)

Parameter:
x : Non-negative integer whose gcd has to be computed.
y : Non-negative integer whose gcd has to be computed.

Returns: An absolute/positive integer value after calculating the GCD of given parameters x and y.

Exceptions : When Both x and y are 0, function returns 0, If any number is a character, Type error is raised.

代码#1：

# Python code to demonstrate the working of gcd()
    
# importing "math" for mathematical operations 
import math 
    
# prints 12 
print ("The gcd of 60 and 48 is : ", end ="") 
print (math.gcd(60, 48)) 

输出：

The gcd of 60 and 48 is : 12

代码#2：

# Python code to demonstrate the working of gcd()
  
# importing "math" for mathematical operations 
import math 
  
# prints gcd of x, y
print ("math.gcd(44, 12) : ", math.gcd(44, 12))
print ("math.gcd(69, 23) : ", math.gcd(65, 45))

输出：

math.gcd(44, 12) :  4
math.gcd(69, 23) :  5

代码#3：解释异常。

# Python code to demonstrate gcd() 
# method exceptions 
import math 
    
# prints 0 
print ("The gcd of 0 and 0 is : ", end ="") 
print (math.gcd(0, 0)) 
    
# Produces error 
print ("\nThe gcd of a and 13 is : ", end ="") 
print (math.gcd('a', 13)) 

输出：

The gcd of 0 and 0 is : 0

The gcd of a and 13 is :
