Given numbers are 221, 512, 544, 421

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

Apply this formula for all numbers.

Step1:

LCM(221, 512) = 113152

GCD(221, 512) = ( 221 x 512 ) / 113152

= 221 / 512

= 221

Step2:

LCM(1, 544) = 544

GCD(1, 544) = ( 1 x 544 ) / 544

= 1 / 544

= 1

Step3:

LCM(1, 421) = 421

GCD(1, 421) = ( 1 x 421 ) / 421

= 1 / 421

= 1

So, Greatest Common Divisor of 221, 512, 544, 421 is 1
