Given numbers are 549, 342, 477, 215

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

Apply this formula for all numbers.

Step1:

LCM(549, 342) = 20862

GCD(549, 342) = ( 549 x 342 ) / 20862

= 549 / 342

= 549

Step2:

LCM(9, 477) = 477

GCD(9, 477) = ( 9 x 477 ) / 477

= 9 / 477

= 9

Step3:

LCM(9, 215) = 1935

GCD(9, 215) = ( 9 x 215 ) / 1935

= 9 / 215

= 9

So, Greatest Common Divisor of 549, 342, 477, 215 is 1
