To find the HCF of two numbers you first need to express them as the product of their prime factors: 12 = 2x2x3 60 = 2x2x3x5 The next step is to identify any common factors. In this case, both numbers have two 2s and a 3 as prime factors. Multiply these together and you get 2x2x3=12 Thus the HCF of 12 and 60 is 12.
To do this you first need to express each number as a product of their prime factors: 36 = 2x2x3x3 60 = 2x2x3x5 The next step is to identify any common prime factors. In this case, both numbers have a 2 a 2 and a 3 as prime factors. Multiply these together and you get 12. Therefore the HCF of 36 and 60 is 12. To find the LCM, multiply the numbers together and divide by the hcf: 36x60/12 = 180 So 180 is the LCM of 36 and 60.
To find the LCM of 3 numbers you first need to split them into their prime factors: 12 = 2x2x3 15 = 3x5 20 = 2x2x5 The next step is to identify any common factors. In this case, two numbers have 3, so we can discard one of these. Two numbers have two 2s, so we can discard 2 of these. Two numbers also have a 5, so we can discard one of these. That leaves us with 2, 2, 3, 5 as the prime factors. Multiplying these together gives: 2x2x3x5 = 60. And therefore 60 is the LCM of 12, 15 and 20.

The GCF of 60 and 60 is 60.
The GCF is 15 - 3x5The LCM is 60 - 2x2x3x5
-60/36=(-2x2x3x5)/(2x2x3x3) = -5/3
