GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(242, 391) = 94622
GCD(242, 391) = ( 242 x 391 ) / 94622
= 242 / 391
= 242
Step2:
LCM(1, 939) = 939
GCD(1, 939) = ( 1 x 939 ) / 939
= 1 / 939
= 1
Step3:
LCM(1, 489) = 489
GCD(1, 489) = ( 1 x 489 ) / 489
= 1 / 489
= 1
So, Greatest Common Divisor of 242, 391, 939, 489 is 1
