Given numbers are 778, 306, 461, 649
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(778, 306) = 119034
GCD(778, 306) = ( 778 x 306 ) / 119034
= 778 / 306
= 778
Step2:
LCM(2, 461) = 922
GCD(2, 461) = ( 2 x 461 ) / 922
= 2 / 461
= 2
Step3:
LCM(1, 649) = 649
GCD(1, 649) = ( 1 x 649 ) / 649
= 1 / 649
= 1
So, Greatest Common Divisor of 778, 306, 461, 649 is 1
