GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(671, 477) = 320067
GCD(671, 477) = ( 671 x 477 ) / 320067
= 671 / 477
= 671
Step2:
LCM(1, 905) = 905
GCD(1, 905) = ( 1 x 905 ) / 905
= 1 / 905
= 1
Step3:
LCM(1, 139) = 139
GCD(1, 139) = ( 1 x 139 ) / 139
= 1 / 139
= 1
So, Greatest Common Divisor of 671, 477, 905, 139 is 1
