To play this game, everyone stands in a circle. One player calls out ‘one’. The next player says ‘two’ and so on. A player who has to call out $3$ or a number which can be divided by $3$ has to say ‘Meow’ instead of the number. One who forgets to say ‘Meow’ is out of the game. The last player left is the winner. Which numbers did you replace with ‘Meow’? $3, 6, 9....$

To play this game, everyone stands in a circle. One player calls out ‘one’. The next player says ‘two’ and so on. One who forgets to say ‘Meow’ is out of the game. Play the game by changing the number to $4$. Now, which numbers did you replace with ‘Meow’?

These numbers are the multiples of $4$.
 

To play this game, everyone stands in a circle. One player calls out ‘one’. The next player says ‘two’ and so on. A person who has to call out $5$ or a number which can be divided by $5$ has to say 'Meow' instead od the number. One who forgets to say ‘Meow’ is out of the game. The last player left is the winner. Which numbers did you replace with 'Meow'? Write any ten multiples of $5$. 

Think of a number. If it is a multiple of $3$, write it in the red circle. If it is a multiple of $5$, write it in the blue circle.

Some numbers are multiples of both $3$ and $5.$

So we can say that they are common to both $3$ and $5.$

Think! If you write the multiples common to $3$ and $5$ in the purple part, then will they still be in both the red and the blue circles??

Which is the smallest among these common multiples?

Repeat the game using the numbers $2$ and $7.$

Write the common multiples of $2$ and $7.$

Putting the multiples of $4$, $6$ and $5$ in the circles.

What common multiples of $5$ and $6$ did you write in the green part?
 

What is the smallest common multiple of $4, 6$ and $5$?
