Given numbers are 549, 261, 253, 636

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

Apply this formula for all numbers.

Step1:

LCM(549, 261) = 15921

GCD(549, 261) = ( 549 x 261 ) / 15921

= 549 / 261

= 549

Step2:

LCM(9, 253) = 2277

GCD(9, 253) = ( 9 x 253 ) / 2277

= 9 / 253

= 9

Step3:

LCM(1, 636) = 636

GCD(1, 636) = ( 1 x 636 ) / 636

= 1 / 636

= 1

So, Greatest Common Divisor of 549, 261, 253, 636 is 1
