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 is the greatest common factor of 14 22 and 28?
Answer: 2 One way to determine the greatest common factor is to find all the factors of the numbers and compare them. The factors of 14 are 1, 2, 7, and 14. The factors of 22 are 1, 2, 11, and 22. The factors of 28 are 1, 2, 4, 7, 14, and 28. The common factors are 1 and 2. Therefore, the greatest common factor is 2. The greatest common factor can also be calculated by identifying the common prime factors and multiplying them together. The prime factors of 14 are 2 and 7. The prime factors of 22 are 2 and 11. The prime factors of 28 are 2, 2, and 7. The prime factors in common are a single 2, so the greatest common factor is 2.
What is the greatest common factor of 14 28 and 56?
gcf(14, 28, 56) = 14
What are the common factors of 28 and 56?
A factor is a divisor - a number that will evenly divide into another number. The greatest common factor of two or more numbers is the largest factor that both numbers have in common.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 28 are 1, 2, 4, 7, 14, and 28.The factors of 56 are 1, 2, 4, 7, 8, 14, 28, and 56.The common factors are 1, 2, 4, 7, 14, and 28. Therefore, the greatest common factor is 28.1/2/4/7/14/28
