GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(394, 489) = 192666
GCD(394, 489) = ( 394 x 489 ) / 192666
= 394 / 489
= 394
Step2:
LCM(1, 121) = 121
GCD(1, 121) = ( 1 x 121 ) / 121
= 1 / 121
= 1
Step3:
LCM(1, 199) = 199
GCD(1, 199) = ( 1 x 199 ) / 199
= 1 / 199
= 1
So, Greatest Common Divisor of 394, 489, 121, 199 is 1
