Given numbers are 221, 818, 228, 473

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

Apply this formula for all numbers.

Step1:

LCM(221, 818) = 180778

GCD(221, 818) = ( 221 x 818 ) / 180778

= 221 / 818

= 221

Step2:

LCM(1, 228) = 228

GCD(1, 228) = ( 1 x 228 ) / 228

= 1 / 228

= 1

Step3:

LCM(1, 473) = 473

GCD(1, 473) = ( 1 x 473 ) / 473

= 1 / 473

= 1

So, Greatest Common Divisor of 221, 818, 228, 473 is 1
