GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(663, 208) = 10608
GCD(663, 208) = ( 663 x 208 ) / 10608
= 663 / 208
= 663
Step2:
LCM(13, 548) = 7124
GCD(13, 548) = ( 13 x 548 ) / 7124
= 13 / 548
= 13
Step3:
LCM(1, 289) = 289
GCD(1, 289) = ( 1 x 289 ) / 289
= 1 / 289
= 1
So, Greatest Common Divisor of 663, 208, 548, 289 is 1
