Given numbers are 221, 428, 857, 608

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

Apply this formula for all numbers.

Step1:

LCM(221, 428) = 94588

GCD(221, 428) = ( 221 x 428 ) / 94588

= 221 / 428

= 221

Step2:

LCM(1, 857) = 857

GCD(1, 857) = ( 1 x 857 ) / 857

= 1 / 857

= 1

Step3:

LCM(1, 608) = 608

GCD(1, 608) = ( 1 x 608 ) / 608

= 1 / 608

= 1

So, Greatest Common Divisor of 221, 428, 857, 608 is 1
