Given numbers are 621, 219, 129, 293

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

Apply this formula for all numbers.

Step1:

LCM(621, 219) = 45333

GCD(621, 219) = ( 621 x 219 ) / 45333

= 621 / 219

= 621

Step2:

LCM(3, 129) = 129

GCD(3, 129) = ( 3 x 129 ) / 129

= 3 / 129

= 3

Step3:

LCM(3, 293) = 879

GCD(3, 293) = ( 3 x 293 ) / 879

= 3 / 293

= 3

So, Greatest Common Divisor of 621, 219, 129, 293 is 1
