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

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
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 The number of groups must be a common factor of 48 and 72
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:
