If `a` and `b` are relatively prime numbers, then what is their HCF?

If a and b are relatively prime numbers,then what is their LCM?

If a and b are relavtively prime then what is their HCF ?

If a and b are two prime numbers then find HCF ( a,b)

If a and b are co-prime numbers, then find the HCF (a, b)

Let S be the set of all points ((a)/(b),(c)/(d)) on the circle with radius 1 centred at (0,0) where a and b are relatively prime integers, c and d are relatively prime integers (that is HCF (a, b) = HCF (c,d) = 1), and the integers b and d are even. Then the set S

If a and b are positive integers, then what is the value of ((alpha)/(HCF(a,b)) ,(b)/(HCF(a,b))) ?

If a,b,c are positive real number such that (a)/(2b-c)=(2b)/(3a+c)=(a)/(b) can be expressed as fraction of relatively prime natural numbers this fraction is: this fraction is:
