00:00:00 Learn how to calculate the GCF, LCM, and LCD in Grade 6 math. Understand the concept of factors and how they can be used to find the common factors of a number.
📚 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.
00:01:05 Learn how to find the GCF, LCM, and LCD in Grade 6 math. Identify factors, find the greatest common factor of 69, and understand common factors.
🔢 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.
00:02:14 Learn how to find the GCF, LCM, and LCD in Grade 6 math. Examples include finding the GCF of numbers and the factors of fractions.
🔑 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.
00:03:22 Learn how to get the least common multiple (LCM) of two numbers. Understand the concept of multiples and apply it to find the LCM of 10 and 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.
00:04:32 Learn how to find the least common multiple and least common denominator in grade 6 math.
🔑 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.
00:05:36 Learn how to find the least common denominator (LCD) for fractions in grade 6 math. Examples included.
✨ 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.
00:06:46 Learn how to find the GCF, LCM, and LCD in Grade 6 math. Achieve success with these important concepts.
🔑 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.
