What is the HCF of 4 and 6 and 8?
2
For example, HCF of 4, 6 and 8 is 2. Here, the highest common factor of 4, 6 and 8 is 2.
How do you find the HCF of 4 numbers?
Solution: Step 1: Divide the largest number by the smallest number. Step 2: Take divisor as new dividend and remainder as the new divisor, i.e. divide the first divisor by the first remainder. Step 3: Proceed till the remainder is zero and the last divisor will be the HCF of the given numbers.
How do you find the LCM when HCF is given?
The formula that shows the relationship between their LCM and HCF is: LCM (a,b) × HCF (a,b) = a × b. For example, let us take two numbers 12 and 8. Let us use the formula: LCM (12,8) × HCF (12,8) = 12 × 8. The LCM of 12 and 8 is 24; and the HCF of 12 and 8 is 4.
What is the HCF of 4 and 8 and 12?
⇒ HCF(4, 8, 12) = 4. Therefore, the HCF of 4, 8 and 12 is 4.
What is the relation between HCF and HCF of two number?
(i) The product of LCM and HCF of the given natural numbers is equivalent to the product of the given numbers. Consider two numbers A and B, then. (ii) The LCM of given co-prime numbers is equal to the product of the numbers since the HCF of co-prime numbers is 1.
Whats the greatest common factor of 2 and 8?
GCF of 2 and 8 by Listing Common Factors There are 2 common factors of 2 and 8, that are 1 and 2. Therefore, the greatest common factor of 2 and 8 is 2.
What is the HCF of two or more numbers?
HCF of two or more numbers is a factor of each of the numbers. HCF of two or more numbers is always less than or equal to each of the numbers. HCF of two or more prime numbers is 1 always. Relation Between LCM and HCF
Here 4 is the highest number that can exactly divide both 4 and 8 , so 4 is the HCF of 4,8. H.C.F can be calculated by any of the following methods,
What is the difference between HCF and least common multiples?
HCF of two or more numbers is the highest common factor of the given numbers. It is found by multiplying the common prime factors of the given numbers. Whereas the least common multiple of two or more numbers is the smallest number among all common multiples of the given numbers.
How do you find the highest common factor of two numbers?
The highest common factor (HCF) is also called the greatest common divisor (GCD) There is more than one method to find the HCF of two numbers. One of the quickest ways to find the HCF of two numbers is to use the prime factorization of each number and then the product of the least powers of the common prime factors will be the HCF of those numbers.
