Given numbers are 306, 680, 403, 459
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(306, 680) = 6120
GCD(306, 680) = ( 306 x 680 ) / 6120
= 306 / 680
= 306
Step2:
LCM(34, 403) = 13702
GCD(34, 403) = ( 34 x 403 ) / 13702
= 34 / 403
= 34
Step3:
LCM(1, 459) = 459
GCD(1, 459) = ( 1 x 459 ) / 459
= 1 / 459
= 1
So, Greatest Common Divisor of 306, 680, 403, 459 is 1
