GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(389, 819) = 318591
GCD(389, 819) = ( 389 x 819 ) / 318591
= 389 / 819
= 389
Step2:
LCM(1, 380) = 380
GCD(1, 380) = ( 1 x 380 ) / 380
= 1 / 380
= 1
Step3:
LCM(1, 621) = 621
GCD(1, 621) = ( 1 x 621 ) / 621
= 1 / 621
= 1
So, Greatest Common Divisor of 389, 819, 380, 621 is 1
