Given numbers are 178, 428, 221, 559

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

Apply this formula for all numbers.

Step1:

LCM(178, 428) = 38092

GCD(178, 428) = ( 178 x 428 ) / 38092

= 178 / 428

= 178

Step2:

LCM(2, 221) = 442

GCD(2, 221) = ( 2 x 221 ) / 442

= 2 / 221

= 2

Step3:

LCM(1, 559) = 559

GCD(1, 559) = ( 1 x 559 ) / 559

= 1 / 559

= 1

So, Greatest Common Divisor of 178, 428, 221, 559 is 1
