Given numbers are 686, 677, 499, 711
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(686, 677) = 464422
GCD(686, 677) = ( 686 x 677 ) / 464422
= 686 / 677
= 686
Step2:
LCM(1, 499) = 499
GCD(1, 499) = ( 1 x 499 ) / 499
= 1 / 499
= 1
Step3:
LCM(1, 711) = 711
GCD(1, 711) = ( 1 x 711 ) / 711
= 1 / 711
= 1
So, Greatest Common Divisor of 686, 677, 499, 711 is 1
