Answer 2

Step-by-step explanation:

First, write a list of the multiples of each number like so:

4

:

4

,

8

,

12

,

16

,

20

,

24

,

28

,

32

,

36

,

40

,

44

,

48

,

52

,

56

.

.

.

7

:

7

,

14

,

21

,

28

,

35

,

42

,

49

,

56

,

63

,

70

,

77

.

.

.

Then you find the first number which

4

and

7

have in common.

4

and

7

have

28

and

56

in common BUT the LCM would be

28

since that's the LEAST common, or the smallest number that they would have in common.

Hope this helped!
