Given numbers are 834, 561, 489, 485
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(834, 561) = 155958
GCD(834, 561) = ( 834 x 561 ) / 155958
= 834 / 561
= 834
Step2:
LCM(3, 489) = 489
GCD(3, 489) = ( 3 x 489 ) / 489
= 3 / 489
= 3
Step3:
LCM(3, 485) = 1455
GCD(3, 485) = ( 3 x 485 ) / 1455
= 3 / 485
= 3
So, Greatest Common Divisor of 834, 561, 489, 485 is 1
