Given numbers are 208, 454, 211, 557

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

Apply this formula for all numbers.

Step1:

LCM(208, 454) = 47216

GCD(208, 454) = ( 208 x 454 ) / 47216

= 208 / 454

= 208

Step2:

LCM(2, 211) = 422

GCD(2, 211) = ( 2 x 211 ) / 422

= 2 / 211

= 2

Step3:

LCM(1, 557) = 557

GCD(1, 557) = ( 1 x 557 ) / 557

= 1 / 557

= 1

So, Greatest Common Divisor of 208, 454, 211, 557 is 1
