Python program to print elements which are multiples of elements given in a list

Given a list, the task here is to write a Python program to extract elements which are multiple of all elements of custom list.

Input : test_list = [4, 24, 8, 10, 12, 23], div_list = [6, 4] 
Output : [24, 12] 
Explanation : 24 and 12 divides 6 and 4 both.

Input : test_list = [4, 24, 8, 10, 12, 23], div_list = [6, 4, 7] 
Output : [] 
Explanation : No elements divides 6, 4 and 7. 

Method 1: Using list comprehension and all()

In this, we perform task of checking for all elements to be multiple using % operator and all(). List comprehension is used to iterate through all the elements.

Python3

# initializing List
test_list = [4, 24, 8, 10, 12, 23]

# printing original list
print("The original list is : " + str(test_list))

# initializing divisor list
div_list = [6, 4]

# using all() to test for all elements
res = [ele for ele in test_list if all(ele % j == 0 for j in div_list)]

# printing result
print("All elements multiple of divisor list : " + str(res))

Output:

The original list is : [4, 24, 8, 10, 12, 23]

All elements multiple of divisor list : [24, 12]

Method 2: Using filter(), lambda and all()

In this, we perform task of filtering using filter() and lambda, rest all the operations are performed like above method.

Python3

# initializing List
test_list = [4, 24, 8, 10, 12, 23]

# printing original list
print("The original list is : " + str(test_list))

# initializing divisor list
div_list = [6, 4]

# using all() to test for all elements
# using filter() and lambda to perform filtering
res = list(filter(lambda ele: all(ele % j == 0 for j in div_list), test_list))

# printing result
print("All elements multiple of divisor list : " + str(res))

Output:

The original list is : [4, 24, 8, 10, 12, 23]

All elements multiple of divisor list : [24, 12]
