Given numbers are 657, 470, 351, 549

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

Apply this formula for all numbers.

Step1:

LCM(657, 470) = 308790

GCD(657, 470) = ( 657 x 470 ) / 308790

= 657 / 470

= 657

Step2:

LCM(1, 351) = 351

GCD(1, 351) = ( 1 x 351 ) / 351

= 1 / 351

= 1

Step3:

LCM(1, 549) = 549

GCD(1, 549) = ( 1 x 549 ) / 549

= 1 / 549

= 1

So, Greatest Common Divisor of 657, 470, 351, 549 is 1
