Unit 6 Indices and Factors Factors

A factor of a positive whole number is any positive whole number that will divide exactly into it. Example:Find all the factors of 20 You can write 20 as: So factors of 20 in increasing order are: 12451020

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 This is unique ? ? ?

Unit 6 Indices and Factors HCF and LCM

The HCF (Highest Common Factor) of two (or more) positive integers is the largest number which is a factor of both (or all) the numbers. 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: Multiples of 60 are: So LCM = 120 Check, 24,48,72,96,120,144,... 60,120,180,240,300,...
