Given numbers are 385, 796, 420, 191
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(385, 796) = 306460
GCD(385, 796) = ( 385 x 796 ) / 306460
= 385 / 796
= 385
Step2:
LCM(1, 420) = 420
GCD(1, 420) = ( 1 x 420 ) / 420
= 1 / 420
= 1
Step3:
LCM(1, 191) = 191
GCD(1, 191) = ( 1 x 191 ) / 191
= 1 / 191
= 1
So, Greatest Common Divisor of 385, 796, 420, 191 is 1
