What is the highest common factor of 28 32?
To find the highest common factor of two numbers, you must first split them into their prime factors. In this case, the numbers 28 and 32 can split as follows: 28 = 2x2x7 32 = 2x2x2x2x2 The next step is to identify all common prime factors. In this case, the common prime factors are two 2s. To find the HCF, you just multiply these together: 2x2=4 Thus the highest common factor of 28 and 32 is 4.
What is the greatest common factors of 12 and 28?
The GCF of 12 and 28 is 4.One way to determine the greatest common factor is to find all the factors of the numbers and compare them.The factors of 12 are 1, 2, 3, 4, 6, and 12.The factors of 28 are 1, 2, 4, 7, 14, and 28.The common factors are 1, 2, and 4. Therefore, the greatest common factor is 4.The greatest common factor can also be calculated by identifying the common prime factors and multiplying them together.The prime factors of 12 are 2, 2, and 3.The prime factors of 28 are 2, 2, and 7.The prime factors in common are 2 and 2, so the greatest common factor is 2 x 2 = 4.Factors of 12: 1 2 3 4 6 12Factors of 28: 1 2 4 7 14 28It is 44
What is the GCF of 28 using prime factors?
There cannot be a greatest common factor (GCF) of just one number. To be common there need to be at least two numbers. If you find all the factors of two or more numbers, and you find some factors are the same ("common"), then the largest of those common factors is the Greatest Common Factor.
What is the greatest common factors of 28 84 and 91?
The GCF of 28, 84, and 91 is 7.
What is the greatest common factors for 56 196 and 28?
The GCF is 28.
