Given numbers are 680, 459, 191, 219
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(680, 459) = 18360
GCD(680, 459) = ( 680 x 459 ) / 18360
= 680 / 459
= 680
Step2:
LCM(17, 191) = 3247
GCD(17, 191) = ( 17 x 191 ) / 3247
= 17 / 191
= 17
Step3:
LCM(1, 219) = 219
GCD(1, 219) = ( 1 x 219 ) / 219
= 1 / 219
= 1
So, Greatest Common Divisor of 680, 459, 191, 219 is 1
