Given numbers are 191, 620, 485, 218

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

Apply this formula for all numbers.

Step1:

LCM(191, 620) = 118420

GCD(191, 620) = ( 191 x 620 ) / 118420

= 191 / 620

= 191

Step2:

LCM(1, 485) = 485

GCD(1, 485) = ( 1 x 485 ) / 485

= 1 / 485

= 1

Step3:

LCM(1, 218) = 218

GCD(1, 218) = ( 1 x 218 ) / 218

= 1 / 218

= 1

So, Greatest Common Divisor of 191, 620, 485, 218 is 1
