There is NO common factor between '13' & '19' , as both these numbers are prime numbers. However, they do have a common MULTIPLE which is 13 X 19 = 247.
13 and 19 are both prime numbers. Their only common factor is ' 1 '.
The first ten prime numbers containing a digit 1 are: 11 13 17 19 31 41 61 71 101 103
13 and 19.
32 is a composite number while 13, 19 and 29 are prime numbers

Both are prime numbers so the answer is 1.
Prime: 19, 23, 59, 103
The least common factor of any set of numbers is 1.
The first ten prime numbers containing a digit 1 are: 11 13 17 19 31 41 61 71 101 103
13 and 19.
19, 23, 13, and 29 are all prime numbers.
the greatest common factor of 19 and 13 is one because 19 or neither 13 are composite
32 is a composite number while 13, 19 and 29 are prime numbers
The common denominator is usually the Lowest (or Least) Common Multiple of the numbers involved. Where two numbers have no common factors then the LCM is simply the product of those numbers. As 19 is a prime number and has no factors in common with 18 then the common denominator is 18 x 19 = 342.
