Given numbers are 687, 621, 971, 227

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

Apply this formula for all numbers.

Step1:

LCM(687, 621) = 142209

GCD(687, 621) = ( 687 x 621 ) / 142209

= 687 / 621

= 687

Step2:

LCM(3, 971) = 2913

GCD(3, 971) = ( 3 x 971 ) / 2913

= 3 / 971

= 3

Step3:

LCM(1, 227) = 227

GCD(1, 227) = ( 1 x 227 ) / 227

= 1 / 227

= 1

So, Greatest Common Divisor of 687, 621, 971, 227 is 1
