GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(381, 318) = 40386
GCD(381, 318) = ( 381 x 318 ) / 40386
= 381 / 318
= 381
Step2:
LCM(3, 538) = 1614
GCD(3, 538) = ( 3 x 538 ) / 1614
= 3 / 538
= 3
Step3:
LCM(1, 486) = 486
GCD(1, 486) = ( 1 x 486 ) / 486
= 1 / 486
= 1
So, Greatest Common Divisor of 381, 318, 538, 486 is 1
