GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(168, 425) = 71400
GCD(168, 425) = ( 168 x 425 ) / 71400
= 168 / 425
= 168
Step2:
LCM(1, 388) = 388
GCD(1, 388) = ( 1 x 388 ) / 388
= 1 / 388
= 1
Step3:
LCM(1, 864) = 864
GCD(1, 864) = ( 1 x 864 ) / 864
= 1 / 864
= 1
So, Greatest Common Divisor of 168, 425, 388, 864 is 1
