Steps to Calculate GCD of 209, 589, 307, 489 using LCM Formula
Given numbers are 209, 589, 307, 489
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(209, 589) = 6479
GCD(209, 589) = ( 209 x 589 ) / 6479
= 209 / 589
= 209
Step2:
LCM(19, 307) = 5833
GCD(19, 307) = ( 19 x 307 ) / 5833
= 19 / 307
= 19
Step3:
LCM(1, 489) = 489
GCD(1, 489) = ( 1 x 489 ) / 489
= 1 / 489
= 1
So, Greatest Common Divisor of 209, 589, 307, 489 is 1
