Given numbers are 663, 559, 548, 690

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(663, 559) = 28509

GCD(663, 559) = ( 663 x 559 ) / 28509

= 663 / 559

= 663

Step2:

LCM(13, 548) = 7124

GCD(13, 548) = ( 13 x 548 ) / 7124

= 13 / 548

= 13

Step3:

LCM(1, 690) = 690

GCD(1, 690) = ( 1 x 690 ) / 690

= 1 / 690

= 1

So, Greatest Common Divisor of 663, 559, 548, 690 is 1
