GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(385, 455) = 5005
GCD(385, 455) = ( 385 x 455 ) / 5005
= 385 / 455
= 385
Step2:
LCM(35, 621) = 21735
GCD(35, 621) = ( 35 x 621 ) / 21735
= 35 / 621
= 35
Step3:
LCM(1, 814) = 814
GCD(1, 814) = ( 1 x 814 ) / 814
= 1 / 814
= 1
So, Greatest Common Divisor of 385, 455, 621, 814 is 1
