Steps to Calculate GCD of 389, 905, 386, 449 using LCM Formula
Given numbers are 389, 905, 386, 449
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(389, 905) = 352045
GCD(389, 905) = ( 389 x 905 ) / 352045
= 389 / 905
= 389
Step2:
LCM(1, 386) = 386
GCD(1, 386) = ( 1 x 386 ) / 386
= 1 / 386
= 1
Step3:
LCM(1, 449) = 449
GCD(1, 449) = ( 1 x 449 ) / 449
= 1 / 449
= 1
So, Greatest Common Divisor of 389, 905, 386, 449 is 1
