GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(207, 388) = 80316
GCD(207, 388) = ( 207 x 388 ) / 80316
= 207 / 388
= 207
Step2:
LCM(1, 558) = 558
GCD(1, 558) = ( 1 x 558 ) / 558
= 1 / 558
= 1
Step3:
LCM(1, 561) = 561
GCD(1, 561) = ( 1 x 561 ) / 561
= 1 / 561
= 1
So, Greatest Common Divisor of 207, 388, 558, 561 is 1
