If `a and b` are two positive integers when `a > b and b` is a factor of a then `HCF` of `( a, b)` is ​

If a and b are positive integers then

If a and b are two negative integers, then the sign of a + b is

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

If a and b are two positive integers, then the relation between their L.C.M and H.C.F will be :

If a and b are positive integers then (HCF(a,b) times LCM (a,b))/(ab) =………..

For any two positive integers 'a' and b, what is the value of HCF (a,b), LCM (a, b)?

If a and b are two odd positive integers such that a >b, then prove that one of the two numbers (a+b)/(2) and (a-b)/(2) is odd and the other is even.

If a and b are positive integers such that a^(2)-b^(4)=2009, find a+b

If a and b positive integers and (a-b)/3.5=4/7, then (a) b > a (b) b = a

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