Most of the time, math questions are about the greatest common factor or the least common multiple, not the least common factor. The least common factor of any two numbers would typically be 1.
The factors of 15 are 1, 3, 5, and 15.
The factors of 9 are 1, 3, and 9.
The greatest common factor is 3.
The prime factors of 15 are 3 and 5.
The prime factors of 9 are 3 and 3.
So, take the 3 and 5 prime factors of 15, and then the second 3 prime factor of 9, multiply them together, so 3 x 5 x 3 = 45 is the least common multiple.

What is the least common factor of 9 12 and 15?
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.
What is the least common factor of 45 and 81?
The least common factor of any numbers is typically 1. The factors of 45 are 1, 3, 5, 9, 15, and 45. The factors of 81 are 1, 3, 9, 27, and 81. The common factors are 1, 3, and 9. The least (smallest) common factor is 1.

What are the greatest common factor and least common multiple of 9 and 15?
3 and 45, respectively.
What is the least common factor of 9 12 18?
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 6, 9, 15, and 18 is 3.
