GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(819, 287) = 33579
GCD(819, 287) = ( 819 x 287 ) / 33579
= 819 / 287
= 819
Step2:
LCM(7, 591) = 4137
GCD(7, 591) = ( 7 x 591 ) / 4137
= 7 / 591
= 7
Step3:
LCM(1, 406) = 406
GCD(1, 406) = ( 1 x 406 ) / 406
= 1 / 406
= 1
So, Greatest Common Divisor of 819, 287, 591, 406 is 1
