What is the greatest common factor of 49 and 70?

One way to determine the greatest common factor is to find all the factors of the numbers and compare them.The factors of 49 are 1, 7, and 49.The factors of 70 are 1, 2, 5, 7, 10, 14, 35, and 70.The common factors are 1 and 7. Therefore, the greatest common factor is 7.The greatest common factor can also be calculated by identifying the common prime factors and multiplying them together.The prime factors of 49 are 7 and 7.The prime factors of 70 are 2, 5, and 7.The common prime factors are a single 7, so the greatest common factor is 7.The GCF is 7.The GCF is: 7


What is the greatest common factor of 28 and 70?

14 One way to determine the greatest common factor is to find all the factors of the numbers and compare them. The factors of 28 are 1, 2, 4, 7, 14, and 28. The factors of 70 are 1, 2, 5, 7, 10, 14, 35, and 70. The common factors are 1, 2, 7, and 14. Therefore, the greatest common factor is 14. The greatest common factor can also be calculated by identifying the common prime factors and multiplying them together. The prime factors of 28 are 2, 2, and 7. The prime factors of 70 are 2, 5, and 7. The prime factors in common are 2 and 7, so the greatest common factor is 2 x 7 = 14.


What are the factors and prime factors of 70?

70 is a composite number because it has factors other than 1 and itself. It is not a prime number. The 8 factors of 70 are 1, 2, 5, 7, 10, 14, 35, and 70. The factor pairs of 70 are 1 x 70, 2 x 35, 5 x 14, and 7 x 10. The proper factors of 70 are 1, 2, 5, 7, 10, 14, and 35 or, if the definition you are using excludes 1, they are 2, 5, 7, 10, 14, and 35. The prime factors of 70 are 2, 5, and 7. The 3 distinct prime factors (listing each prime factor only once) of 70 are 2, 5, and 7. The prime factorization of 70 is 2 x 5 x 7. 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 27 and 70?

Answer:The greatest common factor of 27 and 70 is 1.The common factors of 27 and 70 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 27 are 1, 3, 9, and 27.The factors of 70 are 1, 2, 5, 7, 10, 14, 35, and 70.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 27 are 3, 3, and 3.The prime factors of 70 are 2, 5, and 7.There are no prime factors in common, so the numbers are relatively prime, which means the greatest common factor is 1.The GCF is 1.


What is the least common multiple of 40 70 and 100?

The least common multiple (LCM) of 40, 70, and 100 is 1400. The LCM is the smallest multiple that is divisible by all the given numbers. To find the LCM, we can list out the multiples of each number until we find the smallest multiple that appears in all lists, or we can use prime factorization and take the highest powers of all the prime factors involved.
