Given numbers are 221, 477, 871, 579

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

Apply this formula for all numbers.

Step1:

LCM(221, 477) = 105417

GCD(221, 477) = ( 221 x 477 ) / 105417

= 221 / 477

= 221

Step2:

LCM(1, 871) = 871

GCD(1, 871) = ( 1 x 871 ) / 871

= 1 / 871

= 1

Step3:

LCM(1, 579) = 579

GCD(1, 579) = ( 1 x 579 ) / 579

= 1 / 579

= 1

So, Greatest Common Divisor of 221, 477, 871, 579 is 1
