CAT HCF LCM - Theory There are three numbers a,b, c such that HCF (a, b) = l, HCF (b, c) = m and HCF (c, a) = n. HCF (l, m) = HCF (l, n) = HCF (n, m) = 1. Find LCM of a, b, c. (The answer can be "This cannot be determined"). ...
The formula that expresses the relationship between the Least Common Multiple (LCM) and HCF is given as, LCM (a,b) × HCF (a,b) = a × b; where 'a' and 'b' are the two numbers. What is the HCF of two Consecutive Natural Numbers? The HCF of two consecutive natural numbers is ...
Suppose P and Q are two numbers, then. LCM (P & Q) × HCF (P & Q) = P × Q Relation 2:As HCF of co-prime numbers is 1. Therefore we get that the LCM of given co-prime numbers is equal to the product of the numbers. ...
And HCF and LCM are given to us. Also, one of the numbers is given to us. Thus, we need to find the other number. So, LCM x HCF = product of two numbers => 156 x 4 = 52 × x => x = 12 So, the required answer is 12. Practice Questions 1. Find the HCF of 36, 54,...
