GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(189, 595) = 16065
GCD(189, 595) = ( 189 x 595 ) / 16065
= 189 / 595
= 189
Step2:
LCM(7, 489) = 3423
GCD(7, 489) = ( 7 x 489 ) / 3423
= 7 / 489
= 7
Step3:
LCM(1, 684) = 684
GCD(1, 684) = ( 1 x 684 ) / 684
= 1 / 684
= 1
So, Greatest Common Divisor of 189, 595, 489, 684 is 1
