The lowest common factor of any set of integers is 1.
The least common factor of 30 and 42 is the smallest number that is a factor of both of them and is 1.However, I suspect that you mean either:What is the highest common factor of 30 and 42?ie what is the highest number that is a factor of both 30 and 42: hcf = 6;What is the lowest common multiple of 30 and 42?ie that is the smallest number that is a multiple of both 30 and 42 lcm = 210.
The lowest common denominator of 30 and 42 is 210.
HCF(30, 36, 42) = 6 LCM(30, 36, 42) = 1260
