GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(261, 189) = 5481
GCD(261, 189) = ( 261 x 189 ) / 5481
= 261 / 189
= 261
Step2:
LCM(9, 869) = 7821
GCD(9, 869) = ( 9 x 869 ) / 7821
= 9 / 869
= 9
Step3:
LCM(1, 862) = 862
GCD(1, 862) = ( 1 x 862 ) / 862
= 1 / 862
= 1
So, Greatest Common Divisor of 261, 189, 869, 862 is 1
