Given numbers are 389, 556, 431, 558
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(389, 556) = 216284
GCD(389, 556) = ( 389 x 556 ) / 216284
= 389 / 556
= 389
Step2:
LCM(1, 431) = 431
GCD(1, 431) = ( 1 x 431 ) / 431
= 1 / 431
= 1
Step3:
LCM(1, 558) = 558
GCD(1, 558) = ( 1 x 558 ) / 558
= 1 / 558
= 1
So, Greatest Common Divisor of 389, 556, 431, 558 is 1
