11. Name 8 polygons What is a polygon?
hint…it is not a bird that has disappeared!! (Sorry)

12. The Factors and multiples puzzle
Using the numbers below, complete the grid (you may want to do this in pencil)

14. Write down the first 10 multiples of 9
Factors and multiples
The factors of a number are the whole numbers that divide into it without a remainder.
Find the factors of 20
Find the factors of 84
The multiples of a number can be found by multiplying that number by whole numbers.
Write down the first 10 multiples of 9
Write down the first 5 multiples of 13

15. Product of primes/prime factor decomposition
Sometimes know as prime factor trees

16. Prime Factor Trees 36 3 12 4 3 2 2 36 = 2 × 2 × 3 × 3 = 22 × 32
Show this alternative factor tree for 36.
The prime factor decomposition is the same.
36 = 2 × 2 × 3 × 3
= 22 × 32

17. Write 225 as the product of its prime factors
2 marks

19. Answers
10 = 2x = 2²x 3
14 = 2 x = 3 x 5
20 = 2²x = 2 x 3 x 5
28 = 2²x = 2 x 3 x 7
48 = 24 x = 23 x 7
60 = 2²x 3 x = 23 x 3²
112 = 24 x = 2²x 5 x 7
240 = 24 x 3 x = 2 x 5 x 31
144 = 24 x 3² = 26 x 3

20. The highest common factor (HCF) of two numbers is the highest whole number which divides into both.
The lowest common multiple (LCM) of two numbers is the smallest number that is a multiple of both.

21. We can use the prime factors of a number to find the HCF and LCM of larger numbers.
Find the HCF and LCM of 20 & 84 using factor trees

22. Find the HCF and the LCM of 60 and 294
60 =
2 × 2 × 3 × 5
294 =
2 × 3 × 7 × 7

23. 60 = 2 × 2 × 3 × 5
294 = 2 × 3 × 7 × 7 60
294 2 2 7 3 7 5
HCF of 60 and 294 =
2 x 3 = 6

24. 60 = 2 × 2 × 3 × 5
294 = 2 × 3 × 7 × 7 60
294 2 2 7 3 7 5
HCF of 60 and 294 =
2 x 3 = 6
LCM of 60 and 294 =
2 x 5 x 2 x 3 x 7 x 7 =
2940
