GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(210, 189) = 1890
GCD(210, 189) = ( 210 x 189 ) / 1890
= 210 / 189
= 210
Step2:
LCM(21, 33) = 231
GCD(21, 33) = ( 21 x 33 ) / 231
= 21 / 33
= 21
Step3:
LCM(3, 261) = 261
GCD(3, 261) = ( 3 x 261 ) / 261
= 3 / 261
= 3
So, Greatest Common Divisor of 210, 189, 33, 261 is 3
