In the context of primes and factoriation, every counting number is a factor.
1 is a factor of every number.
Nope.... 1 is a factor of every prime number !
The greatest factor of any number is the number itself. There is no integer that is the greatest factor of every number. One is a factor of every number. One is the GCF of co-prime numbers.
4 3 and 6 have no proper factor in common. Remember that 1 is a factor of every counting number, but not a proper factor of any of them. Greatest common factor questions do not recognise 1 as a proper factor. When talking of primes neither 1 nor the number itself is regarded as a proper factor.
