Given numbers are 198, 292, 685, 489
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(198, 292) = 28908
GCD(198, 292) = ( 198 x 292 ) / 28908
= 198 / 292
= 198
Step2:
LCM(2, 685) = 1370
GCD(2, 685) = ( 2 x 685 ) / 1370
= 2 / 685
= 2
Step3:
LCM(1, 489) = 489
GCD(1, 489) = ( 1 x 489 ) / 489
= 1 / 489
= 1
So, Greatest Common Divisor of 198, 292, 685, 489 is 1
