Given numbers are 679, 251, 621, 173

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

Apply this formula for all numbers.

Step1:

LCM(679, 251) = 170429

GCD(679, 251) = ( 679 x 251 ) / 170429

= 679 / 251

= 679

Step2:

LCM(1, 621) = 621

GCD(1, 621) = ( 1 x 621 ) / 621

= 1 / 621

= 1

Step3:

LCM(1, 173) = 173

GCD(1, 173) = ( 1 x 173 ) / 173

= 1 / 173

= 1

So, Greatest Common Divisor of 679, 251, 621, 173 is 1
