Given numbers are 221, 254, 29, 817

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

Apply this formula for all numbers.

Step1:

LCM(221, 254) = 56134

GCD(221, 254) = ( 221 x 254 ) / 56134

= 221 / 254

= 221

Step2:

LCM(1, 29) = 29

GCD(1, 29) = ( 1 x 29 ) / 29

= 1 / 29

= 1

Step3:

LCM(1, 817) = 817

GCD(1, 817) = ( 1 x 817 ) / 817

= 1 / 817

= 1

So, Greatest Common Divisor of 221, 254, 29, 817 is 1
