GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(686, 979) = 671594
GCD(686, 979) = ( 686 x 979 ) / 671594
= 686 / 979
= 686
Step2:
LCM(1, 137) = 137
GCD(1, 137) = ( 1 x 137 ) / 137
= 1 / 137
= 1
Step3:
LCM(1, 173) = 173
GCD(1, 173) = ( 1 x 173 ) / 173
= 1 / 173
= 1
So, Greatest Common Divisor of 686, 979, 137, 173 is 1
