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

Apply this formula for all numbers.

Step1:

LCM(657, 991) = 651087

GCD(657, 991) = ( 657 x 991 ) / 651087

= 657 / 991

= 657

Step2:

LCM(1, 539) = 539

GCD(1, 539) = ( 1 x 539 ) / 539

= 1 / 539

= 1

Step3:

LCM(1, 306) = 306

GCD(1, 306) = ( 1 x 306 ) / 306

= 1 / 306

= 1

So, Greatest Common Divisor of 657, 991, 539, 306 is 1
