GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(189, 379) = 71631
GCD(189, 379) = ( 189 x 379 ) / 71631
= 189 / 379
= 189
Step2:
LCM(1, 537) = 537
GCD(1, 537) = ( 1 x 537 ) / 537
= 1 / 537
= 1
Step3:
LCM(1, 309) = 309
GCD(1, 309) = ( 1 x 309 ) / 309
= 1 / 309
= 1
So, Greatest Common Divisor of 189, 379, 537, 309 is 1
