The least common factor is a term often mistakenly given to either the greatest common factor (GCF) or the least common multiple (LCM). This term is not often used because it does not describe a useful relationship between numbers. Since 1 evenly divides all integers, 1 is technically the least common factor for any set of integers.
The smallest non-one common factor of 4 and 8 is 2. The least common factor of any set of numbers 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 factors of 8 are 1, 2, 4, and 8. The factors of 12 are 1, 2, 3, 4, 6, and 12. The common factors of 8 and 12 are 1, 2, and 4. Therefore, the least (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 least common factor of 5 and 8 is 1. The least common factor of any set of integers is 1.
They are: 4 and 24 respectively
The least common factor is: 1
The least common factor of any set of integers is 1.
The least common factor of any set of integers is 1.
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.
The least common factor of any set of positive integers is 1.
The least common factor of any set of positive integers is 1.
The least common factor of any set of positive integers 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.
