The least common factor of any set of positive integers is 1.
The least common multiple is 24. The greatest common factor is 4.
The least common factor of any set of integers is 1.
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.
The least common factor of any set of integers is 1.
The least common factor of 8 and 28 is 2.
The least common factor is: 1

The factors of 8 are 1, 2, 4, and 8. The factors of 16 are 1, 2, 4, 8, and 16. The common factors of 8 and 16 are 1, 2, 4, and 8. The least (smallest) common factor is 1.

The least common multiple of two numbers is the product of the two numbers divided by their greatest common factor. The greatest common factor of 4 and 8 is 8. (See related question "What is the greatest common factor of 4 and 8?" for this calculation.) So, the least common multiple is 4 x 8 ÷ 4 = 8. Common multiples of 4 and 8 include 8, 16, 24, 32, 40, 48, 56, 64, 72, 80, etc. Although 16 is a common multiple, it is not the least common multiple.
The factors of 3 are 1 and 3. The factors of 8 are 1, 2, 4, and 8. The only common factor is 1. Therefore, the least (smallest) common factor is 1.
