Since all common factors of a set of numbers are actually factors of their , it is often faster to: of the numbers. Find all factors of that . These are your common factors. 3. Step-by-Step Guide to Finding ƯCLN To find the of numbers greater than 1, follow these three steps:

In Vietnamese Grade 6 mathematics, (Luyện tập Ước chung) refers to practicing exercises related to finding Common Factors of two or more numbers. 1. Core Definitions Factor (Ước): If a natural number is divisible by a natural number is a multiple of is a factor of

Identify the prime factors that are common to all numbers. Luyện tập ƯC

A class has 48 female students and 72 male students. They want to divide into groups so that the number of males and females in each group is equal. What is the maximum number of groups possible?

A number is a common factor of two or more numbers if it is a factor of all those numbers. Example: Factors of 6 are . Factors of 8 are . Their common factors are Since all common factors of a set of

The number of groups must be a common factor of 48 and 72. To find the maximum number of groups, we find the Calculation: Answer: They can be divided into a maximum of 24 groups. 5. Summary Table Example: (12, 18) Ư (Factor) Numbers a is divisible by Ư(12) = {1, 2, 3, 4, 6, 12} ƯC (Common Factor) Shared factors ƯC(12, 18) = {1, 2, 3, 6} ƯCLN (Greatest CF) Largest shared factor ƯCLN(12, 18) = 6

The practice of Luyện tập ƯC involves identifying the shared divisors of multiple numbers, typically by finding the Greatest Common Factor ( ) first and then listing its divisors. Core Definitions Factor (Ước): If a natural number

Decompose each number into its prime factors.
