The least common factor of any set of positive integers is 1.
180
The GCF is 2. The least common factor of any set of positive integers is 1.
Multiples of 6: 6, 12, 18, 24, 30, 36, ................ Multiples of 10: 10, 20, 30, 40, ................ 30 is the LCM (least common multiple) of 6 and 10. correct but LCM stands for lowest common multiple...
Using prime factorisation: 12 = 2² x 3 15 = 3 x 5 →hcf = 3 →lcm = 2² x 3 x 5 = 60
There cannot be a lowest common factor of just one number. To be common there need to be at least two numbers.
