1 has one factor 1
The greatest common factor is the highest number that divides exactly into two or more numbers. 34: 1, 2, 17, 34 38: 1, 2, 19, 38 The greatest common factor for 34 and 38 is 2.
It is called a "unit". Note: by definition, 1 can not be prime because all prime numbers are divisible by exactly 1 AND itself, with the AND inferring that there is a second factor. therefore all prime numbers have exactly 2 factors, 1 AND itself. 1 is the multiplicative identity
The greatest (or highest) common factor is the highest number that divides exactly into two or more numbers. The greatest common factor of 14 and 15 is 1
The Greatest Common Factor is the highest number that divides exactly into two or more numbers. 10: 1, 2, 5, 10 11: 1, 11 The Greatest Common Factor of 10 and 11 is 1.

The Lowest Common Factor of ANY set of numbers is 1 - it is the smallest positive integer that divides exactly into each of the numbers which will always be 1. Perhaps you meant either: HIGHEST Common Factor - the greatest integer which divides exactly into each of the numbers; HCF(5, 7, 10) = 1 However, I suspect that you really wanted the Lowest Common MULTIPLE which is the smallest number into which all the numbers divide exactly; LCM(5, 7, 10) = 70.
Prime numbers are any numbers with 2factors exactly, 1, and themselves. Those are: 2,3,5, and 7. 1 is not considered prime because it has only 1 factor.
That's a common factor.
1 has one factor 1
I think you already did. Prime numbers have exactly two factors. 1 is not a prime number because it has only one factor.

All prime numbers have a common factor of 1.
1 is a factor of every whole number, and the gcf of two numbers can be 1 if there is no larger factor common to both numbers.
