Given numbers are 207, 831, 209, 489
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(207, 831) = 57339
GCD(207, 831) = ( 207 x 831 ) / 57339
= 207 / 831
= 207
Step2:
LCM(3, 209) = 627
GCD(3, 209) = ( 3 x 209 ) / 627
= 3 / 209
= 3
Step3:
LCM(1, 489) = 489
GCD(1, 489) = ( 1 x 489 ) / 489
= 1 / 489
= 1
So, Greatest Common Divisor of 207, 831, 209, 489 is 1
