What is the HCF of 15 35 and 20?
5
What two numbers have a LCM of 20 and HCF of 2?
The answer is 4 and 10.
What are HCF of 20 and 30?
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.
What is the HCF of 10 20 35?
5 (leaves you with 2, 4 and 7)
What is HCF and how do you work it out?
The HCF is the Highest Common Factor. Working it out: 1. Choose two numbers and list all the factors of each number in a straght line like this: 20: 1, 2, 4, 5, 10, 20 15: 1, 3, 5, 15 2. find the highest number that appears in both lines. In this case the answer is 5. Does this answer your question?
Hcf of 10 and 15?
The GCF is 5.
What is the hcf between 15 and 20?

Hcf of 20 and 30?
HCF is the highest common factor of two or more numbers. HCF of 20 and 30 is 10.
What is the HCF for 15 and 20?
it is 5
What are the HCF of 15 and 20?
To find the HCF, you first have to express both numbers as the product of their prime factors: 15 = 3x5 20 = 2x2x5 The next step is to identify any common prime factors. In this case both numbers have a 5 as a prime factor. Therefore the HCF of 15 and 20 is 5.
