2 and 20 have an HCF of 2 and an LCM of 20. You could also use 4 and 10.
HCF is the highest common factor of two or more numbers. HCF of 20 and 30 is 10.
To find the HCF of 20 and 30, break them down into their prime factors: 20 = 2x2x5 30 = 2x3x5 The next step is to identify any common prime factors. In this case both numbers have a 2 and a 5 as prime factors. Multiply these together and you get: 2x5 = 10 Therefore the HCF of 20 and 30 is 10.
hcf(18, 30) = 6.
The HCF of 30 and 105 is 15.
