The factors of 6 are 1, 2, 3, and 6. The factors of 18 are 1, 2, 3, 6, 9, and 18. The common factors of 6 and 18 are 1, 2, 3, and 6. Therefore, the least common factor (the smallest common factor) is 1.
The factors of 6 are 1, 2, 3, and 6. The factors of 8 are 1, 2, 4, and 8. The factors that they have in common are 1 and 2. The least (or lowest) common factor is 1. Note: The least common factor of two or more positive integers will always be 1.
The factors of 6 are 1, 2, 3, and 6. The factors of 9 are 1, 3, and 9. The common factors of 6 and 9 are 1 and 3. Therefore, the least (smallest) common factor is 1.
The factors of 12 are: 1, 2, 3, 4, 6, 12 The factors of 18 are: 1, 2, 3, 6, 9, 18 The common factors are: 1, 2, 3, 6 The least of these is 1. There can only be one least. The next smallest is 2.
You need at least two numbers to find a GCF. The factors of 6 are 1, 2, 3, 6. In order to have common factors, you have to have two or more numbers to factor. For example, 6 and 14. The factors of 6 are 1, 2, 3, 6 and the factors of 14 are 1, 2, 7, 14. The common factors are 1 and 2, so the GCF is 2.
In math terminology, "least" means smallest or lowest. The least common factor is the smallest factor that is common to all the numbers being compared. Look at the results in the following examples.Examples:What is the least common factor of 19 and 24?The factors of 19 are 1 and 19.The factors of 24 are 1, 2, 3, 4, 6, 8, 12, and 24.The only common factor is 1, so the least common factor is 1.What is the least common factor of 30 and 36?The factors of 30 are 1, 2, 3, 5, 6, 10, 15, and 30.The factors of 36 are 1, 2, 3, 4, 6, 9, 12, 18, and 36.The common factors are 1, 2, 3, and 6, so the least common factor is 1.What is the least common factor of 28 and 42?The factors of 28 are 1, 2, 4, 7, 14, and 28.The factors of 42 are 1, 2, 3, 6, 7, 14, 21, and 42.The common factors are 1, 2, 7, and 14, so the least common factor is 1.What is the least common factor of 96 and 120?The factors of 96 are 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, and 96.The factors of 120 are 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, and 120.The common factors are 1, 2, 3, 4, 6, 8, 12, and 24, so the least common factor is 1. As you can see, the smallest factor of two or more numbers is 1.
The factors of 3 are 1 and 3. The factors of 5 are 1 and 5. The factors of 6 are 1, 2, 3, and 6. The factors they have in common are only 1, so the least (or lowest) common factor is 1. Note: The least common factor of two or more positive integers will always be 1.
1, 2, 3 and 6
The factors of 30 are 1, 2, 3, 5, 6, 10, 15, and 30. The factors of 36 are 1, 2, 3, 4, 6, 9, 12, 18, and 36. The common factors of 30 and 36 are 1, 2, 3, and 6. Therefore, the least common factor (the smallest common factor) is 1.
The factors of 12 are 1, 2, 3, 4, 6, and 12. The factors of 50 are 1, 2, 5, 10, 25, and 50. The common factors are 1 and 2. Therefore, the least (smallest) common factor is 1.
The factors of 2 are: 1, 2 The factors of 6 are: 1, 2, 3, 6 The common factors are: 1, 2
The least common factor of any set of positive integers is 1.
