Given numbers are 308, 287, 247, 549

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

Apply this formula for all numbers.

Step1:

LCM(308, 287) = 12628

GCD(308, 287) = ( 308 x 287 ) / 12628

= 308 / 287

= 308

Step2:

LCM(7, 247) = 1729

GCD(7, 247) = ( 7 x 247 ) / 1729

= 7 / 247

= 7

Step3:

LCM(1, 549) = 549

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

= 1 / 549

= 1

So, Greatest Common Divisor of 308, 287, 247, 549 is 1
