Given numbers are 395, 831, 766, 689
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(395, 831) = 328245
GCD(395, 831) = ( 395 x 831 ) / 328245
= 395 / 831
= 395
Step2:
LCM(1, 766) = 766
GCD(1, 766) = ( 1 x 766 ) / 766
= 1 / 766
= 1
Step3:
LCM(1, 689) = 689
GCD(1, 689) = ( 1 x 689 ) / 689
= 1 / 689
= 1
So, Greatest Common Divisor of 395, 831, 766, 689 is 1
