Given numbers are 389, 361, 547, 678
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(389, 361) = 140429
GCD(389, 361) = ( 389 x 361 ) / 140429
= 389 / 361
= 389
Step2:
LCM(1, 547) = 547
GCD(1, 547) = ( 1 x 547 ) / 547
= 1 / 547
= 1
Step3:
LCM(1, 678) = 678
GCD(1, 678) = ( 1 x 678 ) / 678
= 1 / 678
= 1
So, Greatest Common Divisor of 389, 361, 547, 678 is 1
