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:
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? Luyện tбєp ЖЇC
Identify the prime factors that are common to all numbers. Since all common factors of a set of
This is the largest number in the set of common factors. 2. How to Find Common Factors (ƯC) There are two primary methods used in practice: Method 1: Direct Listing (For small numbers) List all factors of each number. Identify the numbers that appear in all lists. What is the maximum number of groups possible
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
