Given numbers are 819, 280, 650, 489
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(819, 280) = 32760
GCD(819, 280) = ( 819 x 280 ) / 32760
= 819 / 280
= 819
Step2:
LCM(7, 650) = 4550
GCD(7, 650) = ( 7 x 650 ) / 4550
= 7 / 650
= 7
Step3:
LCM(1, 489) = 489
GCD(1, 489) = ( 1 x 489 ) / 489
= 1 / 489
= 1
So, Greatest Common Divisor of 819, 280, 650, 489 is 1
