The GCF is 1.
It is 1 but the highest common factor is 19
The GCF is 1.
the greatest common factor of 19 and 13 is one because 19 or neither 13 are composite
13 and 19 are both prime numbers. Their only common factor is ' 1 '.
It is: 1
There is no highest common factor for a single number. Common means same or like, where in this case you cannot have an item same to nothing. You need to compare between two numbers. For example, the highest common factor of 19 and 323 (17x19) is 19.
Both values are prime, thus we conclude that the GCF (and the only common factor) is 1.
38=1*2*19 58=1*2*29 highest common factor is 2
The greatest common factor (GCF) of 19 and 13 is 1. This is because 19 and 13 are both prime numbers, meaning they are only divisible by 1 and themselves. Since there are no other common factors between 19 and 13 besides 1, the GCF is 1.
26 greatest factor is itself, 19 is a prime number so it is 19...they dont have a same common factor but 26 x 19 is 494...
Factors of 9: 1, 3, 9Factors of 19: 1, 19GCF (9, 19) = 1
It is 1 because 7 and 19 are prime numbers
