19 and 13 are prime numbers. Therefore, the greatest common factor is 1.
1 is, because 19 is prime
The least common multiple of 16 and 19 is their product, 304. The numbers are co-prime, i.e. have no common factor, so the LCM is their product.
494 is a composite number because it has factors other than 1 and itself. It is not a prime number.The 8 factors of 494 are 1, 2, 13, 19, 26, 38, 247, and 494.The factor pairs of 494 are 1 x 494, 2 x 247, 13 x 38, and 19 x 26.The proper factors of 494 are 1, 2, 13, 19, 26, 38, and 247 or,if the definition you are using excludes 1, they are 2, 13, 19, 26, 38, and 247.The prime factors of 494 are 2, 13, and 19.The 3 distinct prime factors (listing each prime factor only once) of 494 are 2, 13, and 19.The prime factorization of 494 is 2 x 13 x 19.NOTE: There cannot be common factors, a greatest common factor, or a least common multiple because "common" refers to factors or multiples that two or more numbers have in common.
1729 is a composite number because it has factors other than 1 and itself. It is not a prime number.The 8 factors of 1729 are 1, 7, 13, 19, 91, 133, 247, and 1729.The factor pairs of 1729 are 1 x 1729, 7 x 247, 13 x 133, and 19 x 91.The proper factors of 1729 are 1, 7, 13, 19, 91, 133, and 247 or,if the definition you are using excludes 1, they are 7, 13, 19, 91, 133, and 247.The prime factors of 1729 are 7, 13, and 19.The 3 distinct prime factors (listing each prime factor only once) of 1729 are 7, 13, and 19.The prime factorization of 1729 is 7 x 13 x 19.NOTE: There cannot be common factors, a greatest common factor, or a least common multiple because "common" refers to factors or multiples that two or more numbers have in common.
the greatest common factor of 19 and 13 is one because 19 or neither 13 are composite
It is 1 but the highest common factor is 19
The factors of 17 are 1 and 17. The factors of 19 are 1 and 19. The only common factor is 1. Therefore, the least (lowest) common factor is 1 and the greatest (highest) common factor is 1.
The least common factor is: 1
The least common factor of any set of integers is 1.
19 and 13 are prime numbers. Therefore, the greatest common factor is 1.
13 and 19 are both prime numbers. Their only common factor is ' 1 '.
The least common factor of any set of numbers is 1.
The least common factor of any set of numbers is 1.
The least common factor is: 1
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.
-- The least common factor of any group of whole numbers is always ' 1 '.-- The greatest common factor of 15, 19, and 20 also happens to be ' 1 '.
