GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(669, 847) = 566643
GCD(669, 847) = ( 669 x 847 ) / 566643
= 669 / 847
= 669
Step2:
LCM(1, 349) = 349
GCD(1, 349) = ( 1 x 349 ) / 349
= 1 / 349
= 1
Step3:
LCM(1, 197) = 197
GCD(1, 197) = ( 1 x 197 ) / 197
= 1 / 197
= 1
So, Greatest Common Divisor of 669, 847, 349, 197 is 1
