Given numbers are 227, 643, 225, 818

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

Apply this formula for all numbers.

Step1:

LCM(227, 643) = 145961

GCD(227, 643) = ( 227 x 643 ) / 145961

= 227 / 643

= 227

Step2:

LCM(1, 225) = 225

GCD(1, 225) = ( 1 x 225 ) / 225

= 1 / 225

= 1

Step3:

LCM(1, 818) = 818

GCD(1, 818) = ( 1 x 818 ) / 818

= 1 / 818

= 1

So, Greatest Common Divisor of 227, 643, 225, 818 is 1
