☼ Euclidean Algorithm : Of ‘d’ is the H.C.F. of two positive integers ‘a’ and ‘b’, then there exists unique integers ‘m’ and ‘n’ such that d = am + bn.
e.g. (15, 21) = 3 <...
☼ To find L. C. M. of Given Numbers :
■ L. C. M. by Definition : Write all the multiples of each number and take common multiples of all multiples and then select the least …
