Given numbers are 686, 854, 677, 829
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(686, 854) = 41846
GCD(686, 854) = ( 686 x 854 ) / 41846
= 686 / 854
= 686
Step2:
LCM(14, 677) = 9478
GCD(14, 677) = ( 14 x 677 ) / 9478
= 14 / 677
= 14
Step3:
LCM(1, 829) = 829
GCD(1, 829) = ( 1 x 829 ) / 829
= 1 / 829
= 1
So, Greatest Common Divisor of 686, 854, 677, 829 is 1
