Python numpy.lcm()用法及代码示例

numpy.lcm(arr1, arr2, out = None, where = True, casting = ‘same_kind’, order = ‘K’, dtype = None)：此数学函数可帮助用户计算| arr1 |的lcm值。和| arr2 |元素。

参数：
arr1 / arr2: [array_like]Input array.

返回： LCM of two or more numbers.

代码:

# Python program illustrating  
# lcm() method  
import numpy as np  
  
arr1 = [120, 24, 42, 10] 
arr2 = [2250, 12, 20, 50] 
  
print ("arr1:", arr1) 
print ("arr2:", arr2) 
  
print ("\nlcm of arr1 and arr2:", np.lcm(arr1, arr2)) 
print ("\nlcm of arr1 and 10  :", np.lcm(arr1, 10)) 
                     

输出：

arr1:[120, 24, 42, 10]
arr2:[2250, 12, 20, 50]

lcm of arr1 and arr2:[9000,   24,  420,   50]

lcm of arr1 and 10  :[120, 120, 210,  10]
