Given numbers are 489, 561, 834, 427
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(489, 561) = 91443
GCD(489, 561) = ( 489 x 561 ) / 91443
= 489 / 561
= 489
Step2:
LCM(3, 834) = 834
GCD(3, 834) = ( 3 x 834 ) / 834
= 3 / 834
= 3
Step3:
LCM(3, 427) = 1281
GCD(3, 427) = ( 3 x 427 ) / 1281
= 3 / 427
= 3
So, Greatest Common Divisor of 489, 561, 834, 427 is 1
