Math Lesson: Calculating GCF, LCM, and LCD in Grade 6

📚 In this lesson, we will learn how to get the GCF, LCM, and LCD in grade 6 mathematics.

✨ The greatest common factor (GCF) is the largest number that divides two or more numbers evenly.

🔢 Factors are numbers that can be multiplied together to get another number.

🔢 Factors of 16: 16, 1, 4, 8, and 2.

💡 Introduction to Greatest Common Factor (GCF).

🧩 Finding the GCF of 6 and 9: Common factors are 3 and 1, with 3 being the greatest.

🔑 The GCF (Greatest Common Factor) can be found by identifying the common factors of the given numbers.

🔑 To find the GCF of fractions, we need to determine the factors of both the numerator and the denominator.

🔑 The GCF of 6 and 9 is 3, and the GCF of 8 and 2 is 2.

🔑 The greatest common factor of two numbers is three.

📚 Multiples are numbers that can be divided evenly by another number.

➗ To find the least common multiple (LCM) of two numbers, list down all the multiples of each number and find the smallest number that is common to both lists.

🔑 Multiples are numbers that can be divided evenly by another number.

🔑 The least common multiple (LCM) is the smallest multiple that two or more numbers have in common.

🔑 The least common denominator (LCD) is the smallest multiple that two or more denominators have in common.

✨ To find the least common denominator (LCD), we need to find the common multiples of the denominators.

🔢 The common multiples of 3 and 6 are 6, 12, and 18.

📝 The least common multiple (LCM) is the smallest common multiple, which in this case is 6.

🔑 The video teaches how to find the least common multiple (LCM), greatest common factor (GCF), and least common denominator (LCD).

📚 The LCM is found by determining the smallest number that is a multiple of all given numbers, while the GCF is found by finding the largest number that divides evenly into all given numbers.

🎓 The LCD is the least common multiple of the denominators in a fraction, which is useful for adding or subtracting fractions.
