Given numbers are 838, 477, 549, 689
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(838, 477) = 399726
GCD(838, 477) = ( 838 x 477 ) / 399726
= 838 / 477
= 838
Step2:
LCM(1, 549) = 549
GCD(1, 549) = ( 1 x 549 ) / 549
= 1 / 549
= 1
Step3:
LCM(1, 689) = 689
GCD(1, 689) = ( 1 x 689 ) / 689
= 1 / 689
= 1
So, Greatest Common Divisor of 838, 477, 549, 689 is 1
