Question
Throw two dice together. What are the numbers that turn up on the faces of the dice? Make a two-digit number using them. If it is a multiple of any of the numbers written next to the circles, you can write it in that circle. Then it is your friend’s turn. The one who can write more numbers in 10 rounds is the winner.
Hint: I have 3 and 2 on my dice. If I make 23, it is not the multiple of any of the numbers. So I will make 32, which is a multiple of 4, and write it in the red circle.
Solution
A dice has six faces with numbers 1, 2, 3, 4, 5, and 6.
Using all these numbers taking two at a time we can form the multiples of 6, 4, 5, and 7 as follows:
Multiples of 6: 12, 24, 36, 42
Multiples of 4: 12, 16, 24, 32
Multiples of 5: 15, 25, 35, 45
Multiples of 7: 14, 21, 35, 42

Look at the green boxes in the chart. These show how we can get 12 by multiplying different numbers.
12 = 4 × 3, so 12 is a multiple of both 4 and 3. 12 is also a multiple of 6 and 2, as well as 12 and 1. We say 1, 2, 3, 4, 6, 12 are factors of 12.
