Given numbers are 188, 644, 227, 821

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

Apply this formula for all numbers.

Step1:

LCM(188, 644) = 30268

GCD(188, 644) = ( 188 x 644 ) / 30268

= 188 / 644

= 188

Step2:

LCM(4, 227) = 908

GCD(4, 227) = ( 4 x 227 ) / 908

= 4 / 227

= 4

Step3:

LCM(1, 821) = 821

GCD(1, 821) = ( 1 x 821 ) / 821

= 1 / 821

= 1

So, Greatest Common Divisor of 188, 644, 227, 821 is 1
