GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(779, 428) = 333412
GCD(779, 428) = ( 779 x 428 ) / 333412
= 779 / 428
= 779
Step2:
LCM(1, 807) = 807
GCD(1, 807) = ( 1 x 807 ) / 807
= 1 / 807
= 1
Step3:
LCM(1, 945) = 945
GCD(1, 945) = ( 1 x 945 ) / 945
= 1 / 945
= 1
So, Greatest Common Divisor of 779, 428, 807, 945 is 1
