17. What are the factors of 28?

18. 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

19. Write down the first 10 prime numbers
A prime number is divisible by itself and 1
A prime number must have 2 factors
2,3,5,7,11,13,17,19,23,29

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

21. Prime Factor Trees 36 12 3 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

24. 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

25. Individual study
Choose which areas to revise depending on your own strengths and areas for development.
