Given numbers are 218, 181, 203, 808

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

Apply this formula for all numbers.

Step1:

LCM(218, 181) = 39458

GCD(218, 181) = ( 218 x 181 ) / 39458

= 218 / 181

= 218

Step2:

LCM(1, 203) = 203

GCD(1, 203) = ( 1 x 203 ) / 203

= 1 / 203

= 1

Step3:

LCM(1, 808) = 808

GCD(1, 808) = ( 1 x 808 ) / 808

= 1 / 808

= 1

So, Greatest Common Divisor of 218, 181, 203, 808 is 1
