GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(209, 574) = 119966
GCD(209, 574) = ( 209 x 574 ) / 119966
= 209 / 574
= 209
Step2:
LCM(1, 777) = 777
GCD(1, 777) = ( 1 x 777 ) / 777
= 1 / 777
= 1
Step3:
LCM(1, 764) = 764
GCD(1, 764) = ( 1 x 764 ) / 764
= 1 / 764
= 1
So, Greatest Common Divisor of 209, 574, 777, 764 is 1
