Example: Find all the factors of 20 You can write 20 as: So factors of 20 in increasing order are: 1 2 4 5 10 20 You have finished viewing the presentation Factors Please choose an option Return to Start Presentation 1 Square and Square Roots Presentation 2 Cube and Cube Roots Presentation 3 Index Notation Presentation 4 Rules of Indices Presentation 6 Prime Factors Presentation 7 HCF and LCM Presentation 8 Negative Indices Unit 6 Indices and Factors Prime Factors Any positive whole number can be written uniquely as the product of its prime factors. Example: Write the number 276 as a product of its prime factor ? ? ?

Example: Find the HCF of 120 and 105 So, HCF = 3 x 5 = 15 Check: , The LCM (Lowest Common Multiple) of two (or more) positive integers in the lowest number into which both (or all) of the numbers can divide exactly. Example: Find the LCM of 24 and 60 Multiples of 24 are: 24, 48, 72, 96,120, 144, . . . Multiples of 60 are: 60, 120, 180, 240, 300, . . . So LCM = 120 Check , You have finished viewing the presentation HCF and LCM Please choose an option Return to the Start Presentation 1 Square and Square Roots Presentation 2 Cube and Cube Roots Presentation 3 Index Notation Presentation 5 Negative Indices Presentation 6 Standard Form Presentation 7 Calculations and Standard Form Unit 6 Indices and Factors Negative Indices We define Evaluate Evaluate Evaluate Evaluate You have finished viewing the presentation Negative Indices Please choose an option Return to Start Presentation 1 Square and Square Roots Presentation 2 Cube and Cube Roots Presentation 3 Index Notation Presentation 4 Rules of Indices Presentation 5 Factors Presentation 6 Prime Factors Presentation 7 HCF and LCM
