GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(478, 289) = 138142
GCD(478, 289) = ( 478 x 289 ) / 138142
= 478 / 289
= 478
Step2:
LCM(1, 949) = 949
GCD(1, 949) = ( 1 x 949 ) / 949
= 1 / 949
= 1
Step3:
LCM(1, 388) = 388
GCD(1, 388) = ( 1 x 388 ) / 388
= 1 / 388
= 1
So, Greatest Common Divisor of 478, 289, 949, 388 is 1
