What is the greatest common factor of 3 and 51?
3 is a factor of 51, and 3 is also the largest factor of itself, so 3 is the greatest common factor. The factors of 3 are 1 and 3. The factors of 51 are 1, 3, 17, and 51. The common factors are 1 and 3. Therefore, the greatest common factor is 3. The greatest common factor can also be calculated by identifying the common prime factors and multiplying them together. The prime factor of 3 is 3. The prime factors of 51 are 3 and 17. The common prime factors are a single 3, so the greatest common factor is 3.
Can the greatest common factor of two numbers be prime?
Yes. The greatest common factor of 4 and 10 is 2, which is a prime number. The greatest common factor of 51 and 81 is 3, which is a prime number.
What is the greatest common factor of 51 and 119?
The factors of 51 are 1, 3, 17, and 51. The factors of 119 are 1, 7, 17, and 119. The factors they have in common are 1 and 17. Therefore the greatest common factor is 17. The greatest common factor can also be determined from the prime factors. The prime factors of 51 are 3 and 17. The prime factors of 119 are 7 and 17. The prime factors they have in common are a single 17, so the greatest common factor is 17.
What is the greatest common factor of 26 and 51?
The GCF of 26 and 51 is 1. The prime factors of 26 are 2 and 13. The prime factors of 51 are 3 and 17. There are no factors, other than 1, which are common to 26 and 51.
What is the greatest common factor of 51 and 20?
Greatest common factor of 20 & 51 is 1. Factors of 20 are 1, 2, 4, 5, 10 & 20. Factors of 51 are 1, 3, 17 & 51. The only common factor is 1, so GCF is 1. Alternate method: Prime factorization of 20 = 2x2x5 Prime factorization of 51 = 3x17 From the prime factorizations it is clear that 1 is the GCF of 20 and 51.
What is the greatest common factor of 18 and 51?
The greatest common factor of 18 and 51 is 3.18 ÷ 3 = 651 ÷ 3 = 17Method: One way to determine the greatest common factor is to find all the factors of the numbers and compare them.The factors of 18 are 1, 2, 3, 6, 9, and 18.The factors of 51 are 1, 3, 17, and 51.The common factors are 1 and 3. Therefore, the greatest common factor is 3.The greatest common factor can also be calculated by identifying the common prime factors and multiplying them together.The prime factors of 18 are 2, 3, and 3.The prime factors of 51 are 3 and 17.The prime factors in common are a single 3, so the greatest common factor is 3.The greatest common factor of 51 and 18 is 3
What is the greatest common factor of 34 51 and 82?
The GCF of 34, 51, and 82 is 1.The prime factorization of 34 is 2*17The prime factorization of 61 is 3*17The prime factorization of 82 is 2*41Since the three integers have no common factor, they are coprime, and their GCF is 1.
What is the greatest common factor of 32 and 51 using prime factors?
The greatest common factor can be calculated by identifying the common prime factors and multiplying them together. The prime factors of 32 are 2, 2, 2, 2, and 2. The prime factors of 51 are 3 and 17. There are no prime factors in common, so the numbers are relatively prime, which means the greatest common factor is 1. Another way to determine the greatest common factor is to find all the factors of the numbers and compare them. The factors of 32 are 1, 2, 4, 8, 16, and 32. The factors of 51 are 1, 3, 17, and 51. The only common factor is 1. Therefore, the numbers are relatively prime and the greatest common factor is 1. You can also determine the greatest common factor by looking at the difference between the two numbers, which is 19. The greatest common factor of two numbers cannot be larger than the difference between the two numbers and must be a factor of the difference between the numbers. Since 19 is a prime number, the only factors it has are 1 and 19. Since 32 and 51 are not divisible by 19, the greatest common factor is 1.
What is the greatest common factor of 51 and 73?
73 is a prime number so 51,3x17 and 73 only have the number 1 as the greatest common factor.
Is 51 a prime factor of 306?
No, 51 isn't prime. 17 is the largest prime factor of 306.
What is the greatest common factor of 51 and 85?
The greatest number which divides both 51 and 85 is 17. So, greatest common factor is 17.Alternate method:P.F. of 51 = 3x17P.F. of 85 = 5x17Clearly, from the P.F. of both numbers 17 is the greatest common factor.The GCF is 17.51 and 85's highest common factor is 17.
What is the greatest common factor of 13 and 51?
The greatest common factor of 13 and 51 is 1.The common factors of 13 and 51 are only the number 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 13 are 1 and 13.The factors of 51 are 1, 3, 17, and 51.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. To then obtain the common factors, list all the factors of the greatest common factor.The prime factors of 13 are 1 and 13.The prime factors of 51 are 3 and 17.There are no prime factors in common, so the numbers are relatively prime, which means the greatest common factor is 1.
