GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(863, 969) = 836247
GCD(863, 969) = ( 863 x 969 ) / 836247
= 863 / 969
= 863
Step2:
LCM(1, 621) = 621
GCD(1, 621) = ( 1 x 621 ) / 621
= 1 / 621
= 1
Step3:
LCM(1, 219) = 219
GCD(1, 219) = ( 1 x 219 ) / 219
= 1 / 219
= 1
So, Greatest Common Divisor of 863, 969, 621, 219 is 1
