Is the greatest common factor of 26 and 65 relatively prime?
The GCF of 26 and 65 is 13. 13 is a prime number. "Relatively prime" refers to numbers whose GCF is 1.
Are 14 and 35 relatively prime?
No, 65 and 70 are not relatively prime. Relatively prime numbers only have the number 1 as a common factor. 65 and 70 also have 5 as a common factor, so they are not relatively prime.
What is the highest common factor of 65 and 145?
Answer:The greatest common factor of 65 and 185 is 5.The common factors of 65 and 185 are 1 and 5.Definition: A factor is a divisor - a number that will evenly divide into another number. The common factors of two or more numbers are all the factors that the numbers have in common. The greatest common factor of two or more numbers is the largest factor that the numbers have in common.Methods:One way to determine the common factors and greatest common factor is to find all the factors of the numbers and compare them.The factors of 65 are 1, 5, 13, and 65.The factors of 185 are 1, 5, 37, and 185.The common factors are 1 and 5. Therefore, the greatest common factor is 5.The greatest common factor can also be calculated by identifying the common prime factors and multiplying them together.The prime factors of 65 are 5 and 13.The prime factors of 185 are 5 and 37.The prime factors in common are a single 5, so the greatest common factor is 5.
What is the least common multiple of 65 and 105?
The least common multiple of 13 , 104 = 104
What is the greatest common factor of 14 31 65 and 69?
The greatest common factor of 14, 31, 65, and 69 is 1. You can find this answer in a number of different ways.First, you could notice that 31 is prime, and so its only factors are 1 and 31. Since 31 is not a factor of 19, you know that 1 is the only other possible common factor of the set.If you like, you could instead find the answer by writing the prime factorization of each number in the set. Since there are no common factors other than 1, the GCF of the set is 1.The prime factorization of 14 is 2*7The prime factorization of 31 is 1*31The prime factorization of 65 is 5*13The prime factorization of 69 is 3*23
