The least common factor of any set of integers is 1.
The least common factor of any set of numbers is 1.
The factors of 12 are 1, 2, 3, 4, 6, and 12. The factors of 16 are 1, 2, 4, 8, and 16. The common factors of 12 and 16 are 1, 2, and 4. Therefore, the least common factor (the smallest 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 factors of 16 are 1, 2, 4, 8, and 16. The factors of 64 are 1, 2, 4, 8, 16, 32, and 64. The common factors are 1, 2, 4, 8, and 16. The least (smallest) common factor is 1. The smallest common prime factor is 2.
The least common factor of 4 and 9 is is: 1
The factors of 16 are 1, 2, 4, 8, and 16. The factors of 21 are 1, 3, 7, and 21. The only common factor is 1; they are relatively prime. The least (or lowest) common factor is 1. The greatest (or highest) common factor is 1.
Least common FACTOR would be 2. LCM would be 80.
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 16 are 1, 2, 4, 8, and 16. The factors of 44 are 1, 2, 4, 11, 22, and 44. The common factors are 1, 2, and 4. The lowest common factor is 1.
The least common factor is: 1
The least common factor is: 1
The least common factor is 1 but the highest common factor is 4
