The least common factor of any set of positive integers is 1.
The factors of 24 are 1, 2, 3, 4, 6, 8, 12, and 24. The factors of 33 are 1, 3, 11, and 33. The common factors are 1 and 3. The least (smallest) common factor is 1. The smallest common prime factor is 3.
It is 1 but the hcf is 3

Both numbers must be multiples of 8, since their greatest common factor is 8. The numbers cannot be larger than 24, since it is their least common multiple. One of the numbers is 8. The only other multiples of 8 that are equal to or less than 24 are 16 and 24. 8 and 16 have greatest common factor of 8 but least common multiple of 16, so it cannot be this pair. 8 and 24 have greatest common factor of 8 and least common multiple of 24, so this is the solution.
1 The factors of 24 are 1, 2, 3, 4, 6, 8, 12, and 24. The factors of 35 are 1, 5, 7, and 35. The only common factor of 24 and 35 is 1. Therefore, the least (smallest) common factor is 1, and the greatest (highest) common factor is 1.
The factors of 4 are 1, 2, and 4. The factors of 24 are 1, 2, 3, 4, 6, 8, 12, and 24. The factors they have in common are 1, 2, and 4. So, 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 24 are 1, 2, 3, 4, 6, 8, 12, and 24.The factors of 36 are 1, 2, 3, 4, 6, 9, 12, 18, and 36.The common factors of 24 and 36 are 1, 2, 3, 4, 6, and 12. Therefore, the least (smallest) common factor is 1.The lowest common factor of any set of positive integers is 1.The least common factor of any set of integers is 1.
The factors of 24 are 1, 2, 3, 4, 6, 8, 12, and 24. The factors of 34 are 1, 2, 17, and 34. The common factors are 1 and 2. Therefore, the least (smallest) common factor is 1.
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 Greatest Common Factor (GCF) of 3 and 24 is: 3
The common factor of 24 and 15 is 1 and 3 .
The least common factor of 3 and 12 is 3 though in reality, the least common factor between any two numbers is 1.
