Here are a few questions from LCM & HCF?
1. How many pairs of positive integers x,y exist such that HCF of, x,y = 35 and sum of x and y = 1085?
2. How many pairs of positive integers x,y exist such that HCF(x,y) + LCM (x,y) = 91?
3. Sum of two numbers x,y = 1050. What is the maximum value of the HCF between x and y?Labels: CAT number theory, HCF, LCM
