GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(189, 441) = 1323
GCD(189, 441) = ( 189 x 441 ) / 1323
= 189 / 441
= 189
Step2:
LCM(63, 419) = 26397
GCD(63, 419) = ( 63 x 419 ) / 26397
= 63 / 419
= 63
Step3:
LCM(1, 864) = 864
GCD(1, 864) = ( 1 x 864 ) / 864
= 1 / 864
= 1
So, Greatest Common Divisor of 189, 441, 419, 864 is 1
