Given numbers are 221, 308, 558, 251

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

Apply this formula for all numbers.

Step1:

LCM(221, 308) = 68068

GCD(221, 308) = ( 221 x 308 ) / 68068

= 221 / 308

= 221

Step2:

LCM(1, 558) = 558

GCD(1, 558) = ( 1 x 558 ) / 558

= 1 / 558

= 1

Step3:

LCM(1, 251) = 251

GCD(1, 251) = ( 1 x 251 ) / 251

= 1 / 251

= 1

So, Greatest Common Divisor of 221, 308, 558, 251 is 1
