The least common factor of 3 and 12 is 3 though in reality, the least common factor between any two numbers is 1.
The factors of 12 are 1, 2, 3, 4, 6, and 12. The factors of 27 are 1, 3, 9, and 27. The common factors of 12 and 27 are 1 and 3. 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 21 are 1, 3, 7, and 21. The common factors are 1 and 3. Therefore, the least common factor (the smallest common factor) is 1.
3 and 12
The least common factor of any set of integers is 1.
1 is the only common factor of 3 and 4. 12 is the least common product of 3 and 4.
The factors of 9 are 1, 3, and 9. The factors of 12 are 1, 2, 3, 4, 6, and 12. The factors of 15 are 1, 3, 5, and 15. The common factors of 9, 12, and 15 are 1 and 3. Therefore, the least common factor (the smallest common factor) is 1.
The least common factor of any pair of numbers, including 10 and 12, is 1. The factors of 10 are 1, 2, 5, and 10. The factors of 12 are 1, 2, 3, 4, 6, and 12. The common factors of 10 and 12 are 1 and 2. Therefore, the least common factor (the smallest common factor) is 1.
The least common factor of any set of integers is 1.
3 and 108, respectively.
The factors of 3 are 1 and 3. The factors of 8 are 1, 2, 4, and 8. The factors of 12 are 1, 2, 3, 4, 6, and 12. The factors of 15 are 1, 3, 5, and 15. The only common factor is 1. Therefore, the least (smallest) common factor is 1.
