Which pair of numbers has the greatest common factor of 6?
6 and 12
How do you express the sum of each pair of numbers as a product of the greatest common factor of the numbers and another number?
Pick a pair of numbers. Let's try 30 and 42. Their GCF is 6. 6 x 5 and 6 x 7 By the distributive property, that can be written as 6(5 + 7)
Can the GCF of a pair of numbers be equal to one of the numbers?
Yes, the Greatest Common Factor (GCF) of a pair of numbers can be equal to one of the numbers. This happens when one of the numbers is a multiple of the other number. In such cases, the GCF will be the smaller number itself, as it is the largest number that can evenly divide both numbers. For example, the GCF of 12 and 6 is 6, as 6 is a factor of both numbers.
What is the least common factor of 6?
There are no common factors of 6 because there cannot be common factors without two or more numbers to compare. Common factors are factors that the numbers being compared have in common. Thus, there cannot be a least common factor. In general, the least common factor of two numbers is 1.
What are the lowest common factor of 6 and 8?
The least common factor of any set of numbers is 1.
