You will water both of them on the 28th day because if your multiply 4 & 7 you get 28. You could just do this:

4: 4,8,16,20,24,28

7: 7,14,21,28

once you see that a number is the same on both, then that's the day you will water both of them on the same day

Tapia · Answer 2

The "least common multiple" of 4 and 7 is 28. Beware of anybody who tells you to just multiply them. The least common multiple is not always their product. For example, the least common multiple of 4 and 6 is 12, NOT 24.
