GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(128, 389) = 49792
GCD(128, 389) = ( 128 x 389 ) / 49792
= 128 / 389
= 128
Step2:
LCM(1, 789) = 789
GCD(1, 789) = ( 1 x 789 ) / 789
= 1 / 789
= 1
Step3:
LCM(1, 246) = 246
GCD(1, 246) = ( 1 x 246 ) / 246
= 1 / 246
= 1
So, Greatest Common Divisor of 128, 389, 789, 246 is 1
