How is 4 the HCF of 28 and 60?
To figure out the HCF of 28 and 60, split them up into their prime factors: 28 = 2x2x7 60 = 2x2x3x5 The next step is to identify any common prime factors. In this case, both numbers have two 2s as prime factors. Multiply these together and you get: 2x2 = 4 Therefore 4 is the HCF of 28 and 60.
What is the LCM of 28 and 5?
To find the LCM of 28 and 5 you start by splitting these into their prime factors: 28 = 2x2x7 5 = 5 The next step would be to identify any common factors. In this case, there are none, and so we take all the factors, and multiply them together to find the LCM: 2x2x7x5 = 140 Thus the LCM of 28 and 5 is 140.
What is the least common multiple of 28 and 42 found using prime factorization?
First you need to find the prime factors of 28 and 42. 28= 7x22 42= 7x3x2 Then you multiply 7x3x22, the product of which is 84, which is your answer.
