GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(388, 426) = 82644
GCD(388, 426) = ( 388 x 426 ) / 82644
= 388 / 426
= 388
Step2:
LCM(2, 918) = 918
GCD(2, 918) = ( 2 x 918 ) / 918
= 2 / 918
= 2
Step3:
LCM(2, 489) = 978
GCD(2, 489) = ( 2 x 489 ) / 978
= 2 / 489
= 2
So, Greatest Common Divisor of 388, 426, 918, 489 is 1
