Given numbers are 389, 120, 781, 808
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(389, 120) = 46680
GCD(389, 120) = ( 389 x 120 ) / 46680
= 389 / 120
= 389
Step2:
LCM(1, 781) = 781
GCD(1, 781) = ( 1 x 781 ) / 781
= 1 / 781
= 1
Step3:
LCM(1, 808) = 808
GCD(1, 808) = ( 1 x 808 ) / 808
= 1 / 808
= 1
So, Greatest Common Divisor of 389, 120, 781, 808 is 1
