GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(779, 642) = 500118
GCD(779, 642) = ( 779 x 642 ) / 500118
= 779 / 642
= 779
Step2:
LCM(1, 128) = 128
GCD(1, 128) = ( 1 x 128 ) / 128
= 1 / 128
= 1
Step3:
LCM(1, 703) = 703
GCD(1, 703) = ( 1 x 703 ) / 703
= 1 / 703
= 1
So, Greatest Common Divisor of 779, 642, 128, 703 is 1
