GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(388, 772) = 74884
GCD(388, 772) = ( 388 x 772 ) / 74884
= 388 / 772
= 388
Step2:
LCM(4, 684) = 684
GCD(4, 684) = ( 4 x 684 ) / 684
= 4 / 684
= 4
Step3:
LCM(4, 391) = 1564
GCD(4, 391) = ( 4 x 391 ) / 1564
= 4 / 391
= 4
So, Greatest Common Divisor of 388, 772, 684, 391 is 1
