Grade 6 - Number
Standard 6.N.2 - Practice finding the least common factor (LCF) between two numbers.
Included Skills: Number Properties
Demonstrate understanding of factors and multiples (concretely, pictorially, and symbolically) including: • determining factors and multiples of numbers less than 100 • relating factors and multiples to multiplication and division • determining and relating prime and composite numbers. • Determine the whole-numbered dimensions of all rectangular regions with a given whole-numbered area and explain how those dimensions are related to the factors of the whole number. • Represent a set of whole-numbered multiples for a given quantity concretely, pictorially, or symbolically and explain the strategy used to create the representation. • Explain how skip counting and multiples are related. • Explain why 0 and 1 are neither prime nor composite. • Analyze a whole number to determine if it is a prime number or composite and explain the reasoning. • Determine the prime factors of a whole number and explain the strategy used to determine the factors. • Explain how the composite factors of a whole number can be determined from the prime factors of the whole number and vice versa. • Solve situational questions involving factors, multiples, and prime factors. • Analyze two whole numbers for their common factors. • Analyze two whole numbers to determine at least one multiple (greater than both whole numbers) that is common to both.
