GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(779, 897) = 698763
GCD(779, 897) = ( 779 x 897 ) / 698763
= 779 / 897
= 779
Step2:
LCM(1, 405) = 405
GCD(1, 405) = ( 1 x 405 ) / 405
= 1 / 405
= 1
Step3:
LCM(1, 565) = 565
GCD(1, 565) = ( 1 x 565 ) / 565
= 1 / 565
= 1
So, Greatest Common Divisor of 779, 897, 405, 565 is 1
