What is the greatest common factor of 42 and 55?
Answer:The greatest common factor of 42 and 55 is 1.The common factors of 42 and 55 are only 1.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 42 are 1, 2, 3, 6, 7, 14, 21, and 42.The factors of 55 are 1, 5, 11, and 55.The only common factor is 1. Therefore, the greatest common factor is 1, which means the numbers are relatively prime.The greatest common factor can also be calculated by identifying the common prime factors and multiplying them together.The prime factors of 42 are 2, 3, and 7.The prime factors of 55 are 5 and 11.There are no prime factors in common, so the numbers are relatively prime, which means the greatest common factor is 1.
What is the greatest common factor of 55 and 155?
* The prime factors of 55 are 5 and 11. * The prime factors of 155 are 5 and 31. Therefore the only common factor betwen them is 5. So it is also the highest.5.The GCF is 5.
What is the greatest common factor of 20 55 and 85?
The GCF of 20, 55, and 85 is 5 One way to determine the greatest common factor is to find all the factors of the numbers and compare them. The factors of 20 are 1, 2, 4, 5, 10, and 20. The factors of 55 are 1, 5, 11, and 55. The factors of 85 are 1, 5, 17, and 85. 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 20 are 2, 2, and 5. The prime factors of 55 are 5 and 11. The prime factors of 85 are 5 and 17. The prime factors in common are a single 5, so the greatest common factor is 5.
What are the common factors of 55 and 145?
Answer:The common factors of 55 and 145 are 1 and 5.The greatest common factor of 55 and 145 is 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 55 are 1, 5, 11, and 55.The factors of 145 are 1, 5, 29, and 145.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. To then obtain the common factors, list all the factors of the greatest common factor.The prime factors of 55 are 5 and 11.The prime factors of 145 are 5 and 29.The prime factors in common are only the number 5, so the greatest common factor is 5. The factors of 5 are 1 and 5, which are the common factors.
What are the factors and prime factors of 55?
55 is a composite number because it has factors other than 1 and itself. It is not a prime number.The only factors for 55 are 1, 5, 11, 55The factor pairs of 55 are 1 x 55 and 5 x 11.The proper factors of 55 are 1, 5, and 11 or,if the definition you are using excludes 1, they are 5 and 11.The prime factors of 55 are 5 and 11.The 2 distinct prime factors (listing each prime factor only once) of 55 are also 5 and 11.The prime factorization of 55 is 5 x 11.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.
What is the greatest common factor of 55 33 and 73?
83 is a prime number so the prime factorisation of 83 is 1*83 Therefore the only possible GCF is 1 or 83. But, 83 > 55 so 83 cannot be a factor of 55. Consequently, the only possible common factor is 1. And since 1 is a GCF of all numbers, that is their GCF.
