What is the relation between the LCM and HCF?
(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.
How do you find the HCF of a big number quickly?
First, divide the large number by a small number. If the remainder is left, then divide the first divisor by remainder. If the remainder divides the first divisor completely, then it is the HCF or highest common factor of the given two numbers.
How do you find the HCF in common division method?
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. Therefore, HCF of 24 and 15 is 3.
