GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(381, 549) = 69723
GCD(381, 549) = ( 381 x 549 ) / 69723
= 381 / 549
= 381
Step2:
LCM(3, 831) = 831
GCD(3, 831) = ( 3 x 831 ) / 831
= 3 / 831
= 3
Step3:
LCM(3, 453) = 453
GCD(3, 453) = ( 3 x 453 ) / 453
= 3 / 453
= 3
So, Greatest Common Divisor of 381, 549, 831, 453 is 3
