GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(388, 634) = 122996
GCD(388, 634) = ( 388 x 634 ) / 122996
= 388 / 634
= 388
Step2:
LCM(2, 880) = 880
GCD(2, 880) = ( 2 x 880 ) / 880
= 2 / 880
= 2
Step3:
LCM(2, 168) = 168
GCD(2, 168) = ( 2 x 168 ) / 168
= 2 / 168
= 2
So, Greatest Common Divisor of 388, 634, 880, 168 is 2
