Standard 6.N.2 - Practice finding the greatest common factor (GCF) between two numbers.

Included Skills:

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.
