They are all prime numbers because they have only two factors.
Both values are prime, thus we conclude that the GCF (and the only common factor) is 1.
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 values are prime, thus we conclude that the GCF (and the only common factor) is 1.
13 and 19 are both prime numbers. Their only common factor is ' 1 '.
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.
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.
13 and 19.
The first ten prime numbers containing a digit 1 are: 11 13 17 19 31 41 61 71 101 103
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.
