Short answer: There is none.
There is not a least common factor of a single number, such as 120, because there cannot be any form of common factor without two or more numbers to compare. Common factors are factors that the numbers being compared have in common. The least common factor is the smallest factor that all the numbers being compared have in common. Thus, since there are not two or more numbers to compare, there is not a least common factor.
Note: The least common factor of two or more positive integers is 1.

ReneThe 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 120 and 160 is 2.

What is the greatest common factor of 120 and 160?
The greatest common factor of 90 and 160 is 1090/10 = 9160/10 = 16The GCF of 90 and 160 is 10.
What is the greatest common factor of 160 200?
The greatest common factor of 160 and 200 is 40.
What is the HCF of 120 an 160?
The Highest Common Factor (HCF) of 120 and 160 is the largest positive integer that divides both 120 and 160 without leaving a remainder. To find the HCF, we need to determine the common factors of 120 and 160. The factors of 120 are 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, and 120. The factors of 160 are 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 80, and 160. The largest common factor between 120 and 160 is 40. Therefore, the HCF of 120 and 160 is 40.
What is the hcf of 6 and 160?
Greatest Common Factor or Highest Common Factor (GCF or GCD or HCF) of 6 and 160 is 2.
What is the greatest common factor of 22 and 160?
The greatest common factor of 22 and 160 is 2.
