GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(415, 189) = 78435
GCD(415, 189) = ( 415 x 189 ) / 78435
= 415 / 189
= 415
Step2:
LCM(1, 666) = 666
GCD(1, 666) = ( 1 x 666 ) / 666
= 1 / 666
= 1
Step3:
LCM(1, 388) = 388
GCD(1, 388) = ( 1 x 388 ) / 388
= 1 / 388
= 1
So, Greatest Common Divisor of 415, 189, 666, 388 is 1
