Given numbers are 621, 866, 869, 263

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

Apply this formula for all numbers.

Step1:

LCM(621, 866) = 537786

GCD(621, 866) = ( 621 x 866 ) / 537786

= 621 / 866

= 621

Step2:

LCM(1, 869) = 869

GCD(1, 869) = ( 1 x 869 ) / 869

= 1 / 869

= 1

Step3:

LCM(1, 263) = 263

GCD(1, 263) = ( 1 x 263 ) / 263

= 1 / 263

= 1

So, Greatest Common Divisor of 621, 866, 869, 263 is 1
