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]
