To find the HCF of 36 and 66 you first need to express them as a product of their prime factors: 36 = 2x2x3x366 = 2x3x11The next step is to identify any common prime factors. …In this case, both numbers have a 2 and a 3 as prime factors. Multiply these together, and you get:2x3 = 6Thus the hcf of 36 and 66 is 6.(MORE)

Factors of 84 are 1, 2, 3, 4, 6, 7, 12, 14, 21, 28, 41, and 84 Factors of 60 are 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, and 60 The HCF of 84 and 60 is 12

The first thing you need to do to find the HCF is split each number into its prime factors. 9 = 3x336 = 3x3x4Then you identify any shared factors. In this case, both numbers h…ave two 3s, so those are our shared factors. Multiply these together for our answer:3x3=9Thus the HCF of 36 and 9 is 9.(MORE)

To find the HCF you first have to write the numbers as their prime factors: 36 = 2x2x3x375 = 3x5x5The next step is to identify any common prime factors. In this case both numb…ers have 3 as a prime factor. Thus the HCF is 3.To find the LCM you need to multiply the numbers together and divide by the HCF. 36x75/3 = 900Thus the LCM of 36 and 75 is 900.(MORE)

To do this, you first have to break 84 and 108 down into their prime factors: 84 = 2x2x3x7108 = 2x2x3x3x3The next step is to identify any common prime factors. In this case bo…th numbers have two 2s and a 3 as prime factors. Multiply these together and you get 12.Therefore the HCF of 84 and 108 is 12.(MORE)

The greatest common factor (GCF) is often also called the greatest common divisor (GCD) or highest common factor (HCF). Keep in mind that these different terms all refer to t…he same thing: the largest integer which evenly divides two or more numbers.The greatest common factor of 72, 84, and 132 is 12(MORE)
